Diffesale Grades Of Concrete And Their Applications

ordinary grade of concrete. grade. the mix ratio is It is used as pcc applicationuse: It can be used in the construction of levelling course, bedding for footing, concrete roads, etc. grade. the mix ratio is the water TO cement ratio too much water and not enough cement means concrete will be weaker and less durable. the water to cement ratio is the weight of the water divided by the weight of cement. water litres WC ie 0.5 cement kg the lower the ratio, the stronger the concrete. cement concrete & aggregates australia contents sep 10, 2018 standard grade OF concrete. grade. mix ratio is its is used as rcc applicationuse:- It can be used in construction of slabs, beams, columns, footings, etc. grade. It is used as rcc here is grade of mix ratio and numerical value 10, 15, tc are strength of concrete in knmm. so, if we have grade concrete then we can say that its grade is nmm. and mix proportion is 1.3 which indicates that in this types of mix ratios part is cement, part is sand and part is aggregate has been used to make
