When the water cement ratio is 0.5:1, what is the weight of cement in each cubic meter of cement slurry? How to calculate?

Cement is 1.8kg/l, water is 1kg / L, water cement ratio is the weight ratio of water and cement, the weight of water in 1L cement slurry accounts for 1 / 3, and cement accounts for 2 / 3. Therefore, the volume of water in 1L cement slurry is 1 / 3l, i.e. 1 / 3kg, the volume of cement is 2 / 3l, i.e. 9 / 10kg, and the weight of 1l cement slurry is 37 / 30kg, i.e. 1.2333kg

How much cement is needed for one cubic meter of cement slurry? The water cement ratio is 1:1.5

=1000 / (1 / density of cement) = cement consumption, water consumption = cement consumption * 1.5

1 cubic meter of river sand

Because sand is a mixture of various rocks with different mass, its specific gravity is also different, but it is generally between 1.47 and 2.9
Fine sand in 1.5 ordinary river sand 2.5-2.7
