Why we always take proportion of M20 as 1:1.5:3 ? what will be the effect of changing cement grade or aggregate size on this proportion?

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 […]

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 (High Mobility Grouting)

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 […]

High Quality Cement and its Usage

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, […]
