What is water to cement ratio?
Water/cement ratio law states that the strength of concrete is only dependent upon water/cement ratio provided the mix is workable.Strength of concrete primarily depends upon the strength of cement paste.Similarly, the strength of the paste increases with cement content and decreases with air and water content.
How water cement ratio and workability is related to compaction factor?
If you are talking about shrinkage, then quite a bit. To make concrete, cement and water react together. There is a specific amount of water required to hydrate the concrete. Any water extra must leave the concrete and while it makes the concrete more workable, hurts the concrete is several ways. The volume of the concrete will change by whatever excess water you have added. To get workability, it's always best to use a water reducing admixture.
What is stronger concrete or cement?
Concrete is stronger than cement.It is composed of aggregates (sand and gravel) and cement; and may be cast with reinforcing bar within it (reinforced concrete). Cement is only a part of concrete. Cement has no tensile strength while concrete has compressive and tensile strength.
Why is strength of concrete so important in construction?
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
How does the ratio of sand to cement affect the strength of concrete?
Well, if you have a ratio of cement, water and sand that is about 1:1:2, it can make it stronger. However, add any more sand to that, and the concrete can become brittle, making it weak and easy to break.
What effect has the quantity of mixing water have upon the quality of concrete?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
What factors affect the compressive strength of concrete?
water /cement ratio

What is target strength of concrete?
Target strength is the design strength which is determined by whom ever designed mixture of aggregates and the water/cement ratio.

What is the ratio of cement and sand and crushed stone in mix concrete of M-25?
The ratio of cement, sand and crushed stone in M 25 grade concrete is 1:1:2.In this grade of concrete a compressive strength not less than 25 N/mm2 is achieved in 28 days.
What is mean by pcc in civil engineering?
PCC in construction refers to Plain Cement Concrete, which is used as a preparatory base for laying RCC footing. Though PCC is also concrete, this is lean in nature, the ratio being 1:4:8. The compressive strength achieved with this mix is normally 7.5kN/sq.mm.
How the moisture content of the aggregates obtainable at site affect the water content ratio specified?
Obviously, if the aggregates are in a surface wet condition, meaning the moisture content is greater than the absorption, that surface water increases the water-to-cement ratio and affects strength and durability.
