In M20 grade of concrete, M refers to mix(proportion) and 20 refers to characteristics strength of concrete at the age of 28 days. Actually M20 is a standard mix, means it is mix proportion according to standard materials to be use and a standard working environment on site[up to M30 this standards are : 53 […]
Water-Cement Ratio The water-cement ratio is the weight of water provided in a mix divided by the weight of cementitious materials. The total weight of the water includes all the batch water & free water from the surface of aggregates. Cementitious materials includes portland cement, blended cements & supplementary cementitious materials such as fly ash, […]
Types of Cement used in Construction Industry In addition to ordinary cement, the following are the other varieties of cement. Acid Resistance Cement: This is consists of acid resistance aggregates such as quartz, quartzite’s, etc, additive such as sodium fluro silicate (Na 2 SiO 6 ) and aqueous solution of sodium silicate. This is used […]
This construction video is captured to show you how to estimate quantity for cement, sand and aggregate in a concrete column. Here, the dimension given for front section of column is 300 mm x 300 mm The height for gross section of the plan is 3 Meter. Here, M20 grade concrete ratio is 1:1.5:3 and […]
Get some useful construction tips for finding out the quantity of plaster for a wall. Here, the length of the wall is taken as 6 meter, height is taken as 3 meter and thickness is taken as 12 mm = 0.012 meter. To work out the quantity of plaster, the following formula is used :- […]
There are different types of mortars used in building construction works based on nature of application, binding material, density and special purposes for which it is used. Mortar is a workable paste which is prepared by adding required amount of water to a mixture of binding material (also called matrix) and fine aggregate (also called […]
Cement is the most important construction material which has made modern construction possible. It is majorly used in the construction world. The strength and durability of the structure are mainly dependent on strength of cement. The cost of cement is also more than other construction materials (Coarse aggregates, fine aggregates etc.) and it also affects […]
Cement grouting, also known as slurry grouting or high mobility grouting, is a grouting technique that fills pores in granular soil or voids in rock or soil, with flowable particulate grouts. Depending on the application, Portland cement or microfine cement grout is injected under pressure at strategic locations either through single port or multiple port […]
Cement Grouting in cracks in concrete and masonry: Wide cracks, particularly in mass concrete abutments / piers and masonry substructures can be repaired by filling with portland cement grout. This method is effective in sealing the crack in concrete, but it will not structurally bond cracked sections. Applications of cement grouting: i) When cracks are […]
ABSTRACT: Concrete is a basic building material that will continue to be in demand far into the future. A world without concrete, and its dominant precursor, Ordinary Portland Cement (OPC), is hard to imagine. Although there are different types of concrete that have been developed for use in different applications, their common virtues are familiarity, […]
