The unit of measurement of cement is a bag of 50 kg having a volume of 0.035 cum. The batch boxes are made with the size 35x25x40cm which corresponds to one bag of cement. Nominal mix concretes 1:5:10, 1:4:8, 1:3:6, 1:2:4 and 1;1.5; 3 roughly correspond to M5, M7.5, M 10,M15 and M20 grades of concrete so far as their compressive strength is ...

The practical best water-cement ratio is from about 0.40 to over 0.60. A ratio of 0.3 is made concrete too stiff (unless superplasticizers are used). A ratio of 0.8 makes concrete wet and fairly weak concrete. Normal compressive strengths when concrete is properly cured are: 0.4 w/c ratio –> 5600 psi. 0.8 w/c ratio –> 2000 psi.

source of water in the concrete, workability of the concrete as well as w/c-ratio effect on the strength of the concrete. The laboratory work consisted of the preparation of nine concrete with three different w/c-ratio and each w/c-ratio is divided into three category of air content ranging from 2% to 10% by volume.

Coarse Aggregate = (Coarse Aggregate Part / Concrete Parts ) * Concrete Volume = (3/5.5) * 2 = 1.09 m 3 . Water Cement Ratio. According to IS 10262 (2009), Assuming Water-Cement Ratio for the Concrete as 0.45. Required Amount of Water = W/C Ratio X Cement Volume

There are various grades of concrete available in the market based on these ratios. Some of them are: M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent. "M" stands for "mix". Mix represents concrete with designated proportions of cement, sand and aggregate. And the number following "M" represents compressive ...

Coastcrete is a high speciality concrete designed to withstand the coastal and aggressive environmental conditions which demand the concrete to be highly impermeable and durable. The design of Coastcrete makes use of energy efficient and sustainable mineral additives that make the concrete highly impervious, thereby enhancing corrosion protection to the steel reinforcement.

For wet mortar recommended water-cement ratio varies from 0.4 to 0.6. Further, water requirement depends on any admixture added to mortar to improve its workability. Admixtures must be added as per suppliers specifications. Hence, water required = 5.35 bags x 0.0347 = 0.11 m 3 water = 0.11 x 1000 l = 111 liters of water
