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 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 FOR CRACKS IN CONCRETE AND MASONRY

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 […]
