Watercement ratio wc of 100 040 and 364 respectively It can be seen that the sleeve has the highest watercement ratio so that it will have the most flowable mix pare to the GIN and backfilling mixes that have lower watercement ratios To increase the GIN flowability the mix is added with an admixture Meanwhile the back
COMPRESSIVE STRENGTH vs WATERCEMENT RATION CURVE From the above curve it is found out that the WaterCement Ratio corresponding to the 3825MPa and 43 Grade OPC is or from the Generalized curve of BIS is found out as 040 and as per IS 4562000 is 045 Hence we must take the Free WaterCement Ratio as 040
The ratio of the amount of water to the amount of cement by weight is known as Watercement ratio and the strength of concrete depends on this ratio Water affect the whole properties the durability strength of concrete to a great extent Therefore you need to
Determining the watercement ratio cement content and degree of hydration of hardened concrete Watertocement wc mass ratio is important because it controls the mechanical properties and durability of hardened concrete
Grades of Concrete with Proportion Mix Ratio We use different grades of concrete for different parts of the building We could say the grade of concrete is the only thing we do care lot while concreting
Cement is a binding material which makes a bond between aggregates and reinforcing materials together With the development of technology quality and types of cement have also developed So there are different types of cement for different construction works Types of Cement Followings are the types of cement Ordinary Portland Cement OPC
By Raj Mohammad Khan Following table shows the M30 Mix Designs as per IS102622009 hope this helps all civil engineers here
PPC and OPC Cement difference PPC is a pozzolona portland cement whereas OPC is an ordinary portland cement Know more about the difference grade of both cement type sand its use for type of constructions Comparative lower WaterCement ratio provides an added advantage for the further increase of pressive strength of the concrete
Then you need to know the proportion of the cement and sand in the mortar Lets assume out required mortar quantity is 100 cubic feet and the ratio of cement and sand in the mortar is 14 When we say the cementsand ratio is 14 we mean that the mortar contains one part of cement and four parts of sand
Three brands of cement were chosen for the study form the list of tested cements For detailed investigations a number of cement concrete mixes were designed using four different quantities of cement 360 kg 380 kg 400 kg and 420 kg and various water cement ratios viz 045 050 055 and 060 The results are summarized at Tables 3 4 5
