How to Conduct a Field Test of Cement at the Site?

Image
There are several tests for cement that can be carried out at the construction site such as color test, rubbing test, floating test, etc. These tests are indicative of the quality of cement to be used for concrete works. Following are the field tests used for minor construction works: First, open the cement bag. Please take a good look at the cement. Make sure that there should not be any visible lump present inside the cement bag. The color of cement should be Greenish Grey. Thrust your hand into the cement bag, and you must give a cool feeling. Then take a pinch of cement and feel it in between your two fingers, then you should give a very smooth feeling and not a gritty feeling. Take one hand full of cement and immediately through it in a bucket full of water. Cement Particles should be float on the surface of the water before it sinks in the water.  Take 100gm of cement sample and a small quantity of water and make a considerably stiff paste of it, then pat a cake w

For any nation whether developed or developing this is mandatory for them to make their rural areas a major priority for concern. Prosperity of nation lies in the fact that their rural and backward areas are developed enough to fulfill the necessities of the residents living there. So, it is more of a duty of the government and in charge authorities to look out for them and make sure that the rural housing is developed and constructed well. With the advancements in technology and development in the construction sector this is now possible to build Speedy and Low Cost Housing for Rural. MC MUSHONGO INVESTMENT CC Are Low Cost Houses Safe? There is a myth in minds of many people; they think that whenever construction is accompanied with low cost the material used will always be of a low-grade quality. Well this is not the case always. It depends on the intellect of the builder or civil engineer you are working with. He should have the ample amount of knowledge to take such decision

HOW DO WE IMPROVE MASONRY RESISTANCE AGAINST PENETRATION OF WATER?

Image
We select and design type of a wall that is suitable for the degree of forced rain severity anticipated in the location of the project. Completely grouted barrier wall or drainage wall with minimum thickness of 20 mm is recommended for seriously driven rain condition. We Design a drainage Wall to Improve Water Penetration Resistance of Masonry When drainage wall is selected, the wall should be designed in such a way that prevents the water penetration through the outer Wythe of the wall. For the outer Wythe masonry wall maintain its water resistance ability, we  prevent cracks under service Load. When masonry cement is employed,  we make sure that the lower tensile bond strength of the cement should be considered in specifying whether the veneer will crack or not whereas if steel studs are utilized it is recommended to consider the steel flexibility in determining whether the veneer cracks or not. We Design cavity walls to Improve Masonry Water Penetration Resistance If the cavit

Pigments for Concrete: Types, Purposes, and Influences

Image
Pigments are fine dry powder or slurry or aqueous suspension that added to the concrete ingredients to produce colors, other than the normal grey color. It is added during batching as a liquid or finely divided colored inert powder. Pigments can be natural or synthetic, organic or inorganic. Synthetic pigments are more stable and color fast. Examples of pigments are iron oxide (black, bround, red, yellow of varying particle size and shape), chromix oxide (green), titanium dioxide (white), phthalocyanine (blue, green). Wetness  and alkalinity of concrete can be aggressive environment to pigments. That is why it is very important to use pigments designed for use in concrete. Plasticizers may be introduced to concrete mixture in which pigments are used in order to reduce water demand and other constituents that reduce the occurrence of surface efflorescence and minimize color fade caused by UV light. Types of pigments 1. Iron Oxide Pigments  Iron oxide pigments are widely utilized but it

How do Mc Mushongo investment cc Select Soil Improvement Method Based on Soil Types?

Image
1. We do  Soil Replacement The soil replacement method is applicable for soft soil. There are two primary techniques for soil replacement: removal and replacement of the soil and soil displacement. This is only suitable for any soft or weak soil, provided that the soft soil layer is near the surface, groundwater can be lowered economically or the soil layer is located above groundwater, and the weak soil thickness is not greater than 9 m. It involves the removal of soft soil and replacing it with structural fill during grading operations. Soil displacement includes overloading very soft soil until it shears and is displaced by firmer fill. 2.  We water Removal The water removal method is appropriate for sites with an underlying compressible cohesive soil layer. There are four techniques by which water is removed from the soil to improve its strength: 1. Trenching technique 2. Preloading technique 3. Preloading with vertical drain 4. Electro-osmosis 2.1 Trenching Technique Excavation of

Hairline Crack in Concrete - Causes, Repair and Prevention

Image
  The main cause behind the generation of hairline cracks in concrete is plastic shrinkage which is the rapid depletion of moisture from the fresh concrete within its plastic state.  The causes for these cracks to show up can be due to the variations in air temperature, concrete temperature, relative humidity and wind velocity at the surface of the concrete. These factors can cause high rates of evaporation in either hot or cold weather. The other factors that accelerate the chances of hairline cracks are: Water loss due to absorption by subgrade, formwork or aggregate. Bleeding and sedimentation Poor workmanship and negligence Alkali-Aggregate reactions. Type and content of Portland cement and supplementary cementitious materials (fly ash, silica fume,etc.) Type and dosage rate of chemical admixtures. Construction operations like screeding and finishing operations. Prevention of Hairline Cracks in Concrete There are many methods and techniques to prevent this type of crack in case of

Causes of Delamination.

Image
  Causes of Delamination The timing of final trowelling operations is the main factor that leads to delamination of the concrete surface. It is recommended that the finishing operations i.e. trowelling, is supposed to start only after the initial setting time of the concrete. Else, there could be chances to have delamination issues. When the surface is subjected to any sort of load action, these blisters would delaminate out. Going with the finishing processes before the bleeding is completed traps the water or air-voids below the finishing layer. These, as a result, form subsurface voids which make that concrete zone weak. As time passes, these subsurface voids detach with loads. Delamination can also occur due to : The use of a sticky mortar mix with a huge amount of fines. High rate of evaporation. Hastily performed finishing works. When the finishing process is performed hastily, the delamination issue would be widespread over an entire area. This affects larger zones of the concr
