  What is the Right Water-Cement Ratio for Mix Design? Because of this knowledge, Mc Mushongo Investment cc  don't build  houses that will have cracks all over. Different Water-cement ratios are employed for different concrete applications. For high-quality concrete construction, a lower water-cement ratio of 0.4 is employed. For concrete construction like driveways and sidewalks, a w/c ratio ranging from 0.6 to 0.7 is normally used. The practical range of water-cement ratio ranges from 0.3 to 0.8 that gives stiff and weak concrete respectively. Weak concrete means a fairly wet concrete. A compressive strength about 5600psi can be obtained from a concrete of water-cement ratio 0.4. This value will go down to 2000psi if a water-cement ratio of 0.8 is used. How to Choose Water-cement ratio? Based on the exposure conditions and requirements, the w/c ratio is selected either by the customer or by the authority in charge. The w/c ratio can be either taken from the availa...

Foundation is the lowest part of the building or the civil structure that is in direct contact with the soil which transfers loads from the structure to the soil safely. Generally, the foundation can be classified into two, namely  shallow foundation  and  deep foundation. A shallow foundation transfers the load to a stratum present in a shallow depth. The deep foundation transfers the load to a deeper depth below the ground surface. A tall building like a skyscraper or a building constructed on very weak soil requires deep foundation. If the constructed building has the plan to extend vertically in future, then a deep foundation must be suggested. To construct a foundation, trenches are dig deeper into the soil till a hard stratum is reached. To get stronger base foundation concrete is poured into this trench. These trenches are incorporated with reinforcement cage to increase the strength of the foundation. The projected steel rods that are projected outwards act...

 When it comes to construction business, there is nothing like," working from home," It is  not easy to complete a project during this time of Covid-19,  i am talking about the sudden rise of material price, the lockdown and  the limited work force, But goals must be met, purpose must be fulfilled and potential must be released.

In General : Handling or management of construction activity is crucial to prevent the occurrence of construction mistakes at sites. Smallest precautionary steps can help save gigantic losses. These construction errors can appear due to poor-quality material, poor workmanship, inadequate monitoring  etc. So, adopting good construction practices is essential to handle the mistakes and reduce damage, avoid extensive rework, and make sure that the rest of the construction work gets finalized within a specified schedule. Taking responsibility for construction mistakes, appropriate documentation of construction errors, good communication with construction staff, setting repair schedule, and performing project risk assessment are significant practices to handle construction mistakes. Finally, considerations to avoid future mistakes are also important such as the use of automation in construction, improvement of communication tools, and application of good cautions while conducting ...

Mc Mushongo investment cc We determine defective joints through which water travels. We remove mortar from deteriorated joints to a depth of around 1.6cm. We clean joints with water to remove dust and dirt from both joints and bricks. When the wall is still damp, but with no visible water, we  repoint the joints with suitable mortar. We Place the mortar tightly into the joint. The mortar should have a stiff consistency to take its place correctly. To reduce shrinkage, wait for 1 hour or more before the application of the mortar into the joints. After repointing, we keep the masonry in a damp condition for 2 to 3 days. If the bricks are highly absorptive, they may contain a sufficient amount of water to aid materially in curing. We use grouting when less expensive treatment method is desired, but it is less effective, durable, water-resistant than the repointing technique. A grout consists of an equal quantity of Portland cement and sand. We Wet the...

Porotherm clay bricks are horizontally or vertically perforated clay bricks. they are manufactured in variety of sizes (common size is 400x200x200 mm) from natural clay, coal ash, rice husk, and granite slurry. The term porotherm is used for this type of brick due to its desired thermal insulation characteristics. The perforation of the clay brick provides an exception walling system which facilitates thermal insulation resulting in cooler interiors in hot seasons and warm interior conditions in cold seasons. The porotherm clay bricks are easy to use, economical, environmentally friendly, and it can be used for the construction of both non-load bearing walls and load bearing walls. The porotherm bricks are low weight, durable, strong, and possess a satisfactory fire resistance. It can be used with dry mortar which eliminate the need for curing time. Properties of Porotherm Bricks The compressive strength is greater than 3.5MPa High thermal and sound insulation. Low wei...

LEED Certification for Hospitals Leadership in Energy and Environmental Design (LEED) certification is one way to demonstrate adherence to green construction standards.  There are a few steps to be followed for the construction of a hospital in a green and sustainable manner. 1. Site Selection for Hospital Construction. Select a land area that is not located in the middle of the wetlands, on the top of landfills, chemical dumps, or farmlands. Select a site that is easily accessible by public transit. Access to public transportation can facilitate both the staff and patients visiting the hospital. Due to this, there is an improved community presence and reduction in carbon footprint. 2. Avoiding Parking Lots. Parking space for the hospital employees requires a large area of hot black asphalt platform, which contributes to high average global temperature. The objective is to focus on the use of local public transport systems like trains, buses, subways, and bike lanes. 3. Arrange Int...

Role of Architect According to Bamisile (2004), the architect should be visiting site periodically for inspections to ensure that in general, the work being carried out on site is in compliance with architectural designs and specifications. Role of Engineering Consultants. Bamisile (2004) noted that during the construction phase, engineers (geotechnical, structural, electrical and mechanical) should visit the site regularly for inspections to ensure that in general, is in compliance with their engineering drawings, schedules and specification. A Structural Engineer should be concerned with the monitoring and ensuring that the design (structural) performance criteria are met in the construction methods and materials. Similarly, the mechanical and electrical engineer should monitor the type and ways of installing mechanical and electrical installations so as to ensure that it complies with their designs and specifications. Role of the Builder. The core function of a builder in any constr...

  Every player in the construction sector, in one way or the other, is a part of the overall supply chain. The project designer, materials supplier, subcontractors, the main contractor, and the client often act as the links of the supply chain across different construction projects and operations. Construction supply chains (CSC) are known to be complex, and their intricacies keep increasing with the growing magnitude of the project. The complexity further increases with the involvement of more people, i.e., first-tier, second-tier suppliers, and other tiers of sub-contractors, etc. The scope of the project is correlated to the complexity of the supply chain as more manpower, parties, and materials are needed for the completion of the project. Thus, it is essential to implement proper planning, organization, and collaboration between supply chain partners for a seamless supply chain operation and a smooth 1.  Development of Suppliers and Subcontractors Mc Mushongo  ...

Risk management in construction industry is an important part of the project planning and management. Various risks associated with construction projects such as financial risks, environmental risks, socio-economic and construction related risks are studied and dealt in risk management. The volatility and capriciousness of the environment in the construction industry was never hidden from anyone. It’s easily influenced by external factors (technical, design, logistics, physical, operating, environmental, socio-political, force majeure et cetera) which are capable of not only derailing projects but can also create an irreparable aberration. Risk management, therefore, becomes a pivotal instrument that helps us deal with the culling out of various risks, their analyses, and the remedial steps that could be taken to avert them in a particular project. Types of Risks in Construction Project Management The major risks that usually crop up in front of a project manager while helming a ...

The geotechnical investigation for any worksite is preceded by the preliminary geological-geotechnical survey. This consists of an on-site superficial survey, sometimes involving small investigation activities, such as the opening of shallow pits and shafts. Usually, the field visit is preceded by a desk study comprising the collection of existing written and drawn information about the site, topographic and geological charts in particular, and geotechnical charts if available. Currently, the use of two and three-dimensional aerial images obtained from satellite and free web navigation tools is also very useful, particularly for large works outside urban areas, such as roads, dams, and for the stabilization of natural slopes. When dealing with densely populated areas, geotechnical characterization reports for nearby constructions can generally be found, which represent important sources to be collected and checked.

  Thickness of masonry walls in a building is designed based on loads and other factors. Various requirements for suitable thickness of masonry walls are discussed. Requirement for Thickness of Masonry Walls in Buildings There are various requirements regarding the thickness of masonry walls that needs to be considered at the design stage. For example, it is recommended to use constant masonry wall thickness between lateral supports. If masonry wall thickness is changed, it is recommended to extend the thicker wall to the lower support level. Building code requirements and specifications for masonry structure (ACI 530-11) states that, when the thickness of masonry wall constructed from hollow masonry units is changed, then it would be required to provide a layer or several layer of solid masonry units or completely grouted hollow masonry units between thicker masonry wall and the thinner masonry wall. The aim of providing solid masonry course between thicker and thinner ma...
