We don't build houses that produce cracks later.

  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 available data o

What is Foundation in Construction? Purpose and the Functions of Foundations.

Image
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 as the bones

In construction there is no working from home.

 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.

How to Handle Construction Mistakes at Site?

Image
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 cons

How do we repair Leaky Joints in Masonry Walls

Image
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 mas

What is Porotherm Bricks? Properties, Advantages, and Applications

Image
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 weight:

How do Mc Mushongo Investment cc Reduce the Possibility of Crack Development in Concrete?

Image
A Lesson to learn for  all  new contractors in namibia.  The possibility of crack development in different structural concrete elements can be reduced by adopting various design and construction measures. Our method  can help reduce or eliminate the causes responsible for the formation of cracks. Common types of cracks in concrete are • plastic settlement cracks •plastic shrinkage cracks •thermal contraction cracks,  •long-term drying shrinkage cracks  •cracks due to reinforcement corrosion and alkali-aggregate •reactions,  • crazing. We  prevent shrinkage and settlement cracks in plastic concrete through the use of • shrinkage-compensating admixture • sufficient concrete cover • controlled rate of evaporation Moreover, cracks due to thermal contractions and long-term drying shrinkage can be controlled by the proper distribution of  •steel bars,  •provision of expansion joints The quality of concrete constituent materials, concrete placement, compaction, and curing play a crucial role
