Use a ratio of 3 parts sand to 1.5 parts cement. Adding hydrated lime to the mixture will reduce shrinkage cracks. It will also make the mortar more waterproof. If you add lime, the mixture will be 15 gallons of sand, 6.38 gallons of cement and 1.12 gallons of lime. Mix the ingredients together before adding water. Step 2 Mix concrete by using 1 part cement to 2.5 parts sand. Add 0.5 part

When we say the cement-sand ratio is 1:4, we mean that the mortar contains one part of cement and four parts of sand. But when we get or buy cement and sand, we get those in dry condition. After adding water in the cement-sand mix, the volume of sand is reduced. So, when we calculate the quantity of cement and sand in the mortar, we need to consider the reduced volume of the sand. Considering
