The basic mixture for most concrete block projects is a 4-to-1 or 5-to-1 mixture. In essence, four parts (or five) of sand are added to one part of cement, and then water is added to that until you achieve the texture you want for your particular block project.
Feb 28, 2014· This important parameter is called the water/cement ratio or ‘w/c’. Cement hydrates at a ratio of 1 to 0.22 so for every 100g of cement used in a mixture, 22ml of water is required for the cement to hydrate.
