Slump, being property of fresh concrete-mix depends a lot on thewater-cement ratio. The ratio of mass of water to the mass of cement is termed as water-cement ratio. Civil engineers write it as “W/C”. The typical value is around 0.40 to 0.60. ...
Water cement ratio– w/c is the ratio of water to the mass of cement expressed in points with typical values 0.40 and 0.60. So, with a water to cement ratio of 0.45; the amount of water will be 0.45 times the weight of cement. Water not only helps in making a plastic paste of cem...

bed of rivers and other flowing water bodies. This seashore gravel is not only a good choice for ornamental purpose but can also find application in concrete where workability is required. Because of least resistance against particles, the aggregate are also performing in low water-cement ratio. ...
The mix ratio for M25 concrete is typically expressed in terms of the proportions of cement, water, fine aggregate (such as sand), and coarse aggregate (such as gravel or crushed stone) used in the mix. A common mix ratio for M25 concrete is 1:1:2, which refers to a mix that contai...
Lean concrete refers to a mix where the cement used is less than water. Concrete with a high ratio of aggregate to cement is called lean concrete. Technically, the mix is called lean concrete mix if its cement content falls below 10 percent. ...
As we know, when water comes into the equation it increases the weight of the sand. Therefore, wet sand is always heavier and it weights between 1.6 to 1.75 tons per yard or about 3200 to 3500 lb. per yard with a unit weight of 120-130 pounds per cubic foot. ...
Concrete is made when we mix cement, sand, aggregate, and appropriate amount of water in it. Once we add water, the dry ingredients harden and cure to form what we call concrete. The compressive strength of cement is measured in psi or pounds per square inch. We can also know the stren...
