How many bags of cement to make 1m3 of concrete?

Considering a concrete mix proportion (by volume) of. 1:2:4::cement:fine aggregate:Coarge Aggregate . cement required = 01 bag = 36 liters = 50 kg. Fine Aggregate required = 02*36 = 72 ltr.= 72*1.6 = 115 kg. Coarse Aggregate required = 04*36 = 144 ltr.=144*1.45= 209 kg. considering water - cement ratio (w/c) of 0.55 ,water = 0.55*50 = 27.5 kg.

Concrete Workability - A Quick Guide | Readymix2Go

The higher proportion of cement typically means a stronger concrete mix. With the right amount of cement paste the coating of aggregates delivers a better consolidation and finish. If the mix isn't hydrated adequeately you will find the strength development is rather poor. It is also a lot harder to place and finish. However, if too much water is used then this can lead to a negative impact on

By changing the relative proportions of these components, cement manufacturers can control the properties of the product. The primary product of cement hydration is a complex and poorly crystalline calcium-silicate- hydroxide gel (or CSH). A secondary product of hy-dration is calcium hydroxide, a highly crystalline ma-terial. A category of siliceous materials known as pozzolans have little or

Mechanical Properties of Polymer Concrete

Till date no standard mix proportion and aggregate grading criterion are available for polymer concrete and, therefore, a number of optimized mix proportions are reported in the literature. These mixes are based upon various optimization criteria like Fuller's curve, and maximum bulk density, and minimum void content and have been developed for various types of locally available aggregates

What is the maximum cement quantity for m25 grade concrete

Answer by Mihir Salanke: Mix proportion for M25 grade of concrete is 1:1:2(cement:fine aggregates:coarse aggregates). So if you need 4cu.m of M25 concrete, we need to have 1cu.m of cement. So, theoretically, for 1cu.m of M25 concrete, we need to have 0.25cu.m of cement. But in practice, whenever we estimate quantity of cement for concrete
