Weight of cement required can be calculated from multiplying the volume of cement with the bulk density of cement. The bulk density of frequently used cement varieties (both PPC and OPC) is 1440 kg/cu.m. Hence 8 bags of cement required to prepare one cubic meter of M20 grade concrete.

Keeping the water- cement ratio at 0.35 and 0.50 and using super plasticizer (at 15ml per kg of cement) the slump values were determined for both M20 and M25 mixes using river sand and M-sand as fine aggregate.

Learn MoreWhat is M20 grade concrete?

Learn MoreConcrete Mix Design Calculation : M20, M25, M30, M40 Grade Concrete Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible.

Learn MoreTags: plastering sand density , msand density , M Sand , concrete sand density M-Sand is now majorly used in all constructional purposes since it is an economical alternative of river sand and provides better concrete strength compared to it.

Learn MoreMix design aims to achieve good quality concrete at site economically. I. Quality concrete means • Better strength • Better imperviousness and durability • Dense and homogeneous concrete II. Economy a) Economy in cement consumption It is possible to save up to 15% of cement for M20 grade of concrete with the help of concrete mix design. In fact higher the grade of concrete more are the savings. Lower cement content also results in lower heat of hydration and hence reduces shrinkage cracks. b) Be

Learn MoreThe control over these physical properties of manufacturing sand make the concrete require less amount of water and provide higher workable concrete. The less use of water also helps in increasing the strength of concrete, less effort for mixing and placement of concrete, and thus increases productivity of construction activities at site.

Learn MoreDec 10, 2015 · M20 grade concrete mix meet this requirement when M-sand is used as fine aggregate. Bond strength 13.9 MPa for river sand and 14.1 MPa for M-sand Stress-strain characteristics of concrete The strain corresponding to peak stress is 0.0017 and 0.0021 for the concrete using river sand and M-sand respectively. Compressive and flexural strength of ...

Learn MoreThere are two types of MSand i.e., is Concrete MSand & Plastering MSand. You can also use River sand however, you need to sieve them first which is time-consuming & a labor-intensive process. Reply Jun 06, 2019 10:01

Learn MoreM sand can be adulterated in the case when silt or fines are mixed to save cost and using this can lead to weak compression strength in case of concrete and can develop cracks when used for plastering. What are concrete mix proportions if M sand is used? The concrete mix proportions are same as river sand M 20 ( 1 : 1.5 : 3) & M 25 ( 1: 1 : 2)
