If you prepare concrete with your ration then the concrete will have too much sand Too much sand causes shrinkage and this will not give highdensity concrete Hence use 123 for good strength and 12535 for moderate strength If you want to increase strength then reduce the water content and use Chemical admixtures like super plasticisers

A pretty standard recipe for mixing concrete calls for one part of cement to every two parts of sand The result of this recipe assuming that four parts of gravel are also included in the mix is a C20rated concrete Concrete is rated on a number system that indicates how strong the mix is after it has cured for approximately a monthOnline consulting
Bulking of Sand If the moisture is present in the sand then it makes the sand look bulkier which could result in inadequate sand proportion in the concrete ratio If we need to add 1m 3 sand in the concrete mix ratio we take 13 m 3 30 more The reason for that is the moisture content present in the sand makes it a little bulkierOnline consulting
Apr 26 2016nbsp018332Sand finish concrete also called sand washed concrete comes in a wide range of natural color options You can select tones that are reminiscent of granite or tans and browns that evoke the sand at the Oregon coast These tones will blend well with your landscaping scheme lending a soillike look to your patio In fact some homeowners haveOnline consulting

The compressive strength of lower density foamed concrete can be increased to equal that of higher density foamed concrete by increasing the cement content Hamidah et al 2005 On the other hand it is reported that in heavier foamed concrete that accommodates fine aggregate higher s c ratios result in lower compressive strength HamidahOnline consulting
Feb 04 2015nbsp018332Research carried out elsewhere has also proved that increased fine particle content can in many cases be desirable compared to natural sand concrete This is because a high fines content in natural sand usually indicates increased silt clay or shale concentration which is detrimental to both fresh and hardened concrete propertiesOnline consulting
