How many cement use for 1cum concrete for 25grade.Answer amirthaganesan.M.M25 mix has a ratio of 1 cement to 1 sand and 2 stone jelly.I.E 112.This means cement volume is half of stone jelly volume.To prepare 1cu.M of concrete we need 0.0 cu.M of jelly.So we need 0.92 0.45 cu.M of sand.Read More

Up to m25, a nominal mix can be made for small-scale construction where concrete consumption is not high.For m 30 and above grades, design mix should be used.You can see that as the strength of concrete increases, the cement content is constant in proportion but sand, aggregate, and water content are reduced.Read More
Quantity of water is added in m20 grade concrete all grades-as i already given detailed explanation about how to find out the quantity of cement, sand and aggregate required for different grades of concrete.Here you can learn about quantity of water is added in m20 grade concrete all grades.Read More
Concrete grades are determined by concretes compressive strength 28 days after it has been poured.The strength is measured in psi, or pounds per square inch.The greater the psi rating on a mix of concrete, the stronger the concrete will be after it has been poured and set.Read More
Formula for calculating cement consumption for m20 grade.Generally a nominal mix is expressed in terms of aggregate cement ratio.Nominal mix concrete may be used for grades of concrete m20 or.Read More
Concrete technology - concrete is a construction material composed of cement, fine aggregates sand and coarse aggregates mixed with water which hardens with time.Portland cement is the commonly used type of cement for production of concrete.Concrete technology deals with study of properties of concrete and its practical applications.In a building construction, concrete is used for the.Read More
Grades of concrete were compared for design by aci and usbr method using stone dust as fine aggregate.The result indicates that the concrete designed with usbr method using stone dust gives maximum results in compression, flexure and split tensile strength.The results of concrete designed by doe method by using.Read More
Evaluated the land for construction aggregate all grades, concrete aggregate pcc- and ac-grades, or only pcc-grade aggregate.Some of the former study areas were defined by county boundaries, others were defined as p-c regions, and one was nominally defined as a p-c region, but was described as more of a production region.Read More
As per indian standard code their are lots of predefined mix like m20, m25 etc.Generally for slab we use m20 grade of concrete.Here m refer to mix and 20 is the 28 days compressive strength in nmm2.Which is calculated by cube testing.M20 11.53 as we assume by volume 1 vessel is cement, 1.5 vessel is sand and 3 vessel is aggregate.Read More
The nominal mix grades of concrete are generally used for small-scale construction where concrete consumption is not so high.Besides the design mix concrete are those whose mix ratio proportions are obtained from various lab tests by considering the various process in concreting properties of concrete and quality of material used for the preparation of concrete.Read More
In this way, the resulting concrete mass is a void-less or dense mass.The binding property of cement is made use of to give this dense mass a cohesive stone-like character.Concrete is, an artificial stone, in a broad sense.Grading of aggregates is aimed at determining the mean size of the particle in a given batch of aggregates.Read More
The final mix proportions of m-20 grade of concrete become-advertisements.Note 1 the above recommended mix design must be verified, by actual cube tests.2 the mix design is based on the quality and grading of the materials actually supplied, by the client.Read More
