May 17, 2017· Hence We require 1326Kg of 20mm aggregate for 1m 3 of Concrete Amount of Water Required for 1m 3 of Concrete:-For making concrete, required amount of water is added Water quantity is depends upon the climatic factors and workability required We generally maintain 035-050 of water cement ratio

Apr 23, 2014· Water-cementitious materials ratio The ratio of the amount of water, minus the amount of water absorbed by the aggregates, to the amount of cementitious materials by weight in concrete ,

May 28, 2010· Water alone should never be used to improve the workability of fresh concrete Using water to assist in finishing operations or working bleed water back into the top surface of the concrete should also be avoided as these practices will increase the water-to-cement ratio of the top layer of concrete, which will lead to future durability problems

Sep 02, 2017· Best Water Cement Ratio for concrete , How to calculate water cement ratio in concrete | Basic Calculation Hindi - Duration: 5:15 Tutorials Tips 103,424 views 5:15

In concrete, the single most significant influence on most or all of the properties is the amount of water used in the mix In concrete mix design, the ratio of the amount of water to the amount of cement used (both by weight) is called the water to cement ratio (w/c) These two ingredients are responsible for binding everything together The .

What Are the Mix Ratios for Cement and Sand? The basic mix ratio for concrete is one part water, two parts cement and three parts sand An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud

But a water-cement ratio as low as 044 is seldom needed for foundation concrete ACI 318-95, Building Code Requirements for Structural Concrete, requires a maximum water-cementitious materials ratio of 045 for concrete exposed to freezing and thawing in a ,

Oct 29, 2017· in this Video Lecture you are able to Learn what is grade of concrete and water cement ratio in detail and also concrete grade table with water cement ratio To Read Articles :civilglobal .

The discussion about relation between strength of concrete and water/cement ratio has discussed in many posts but aggregate/cement ratio has not yet been discussed and it is believed that this ratio is not very important But actual situation is not always same ,

Water-Cement Ratio is defined as the ratio between the weight of the water to the weight of cement In general terms w/c ratio means, how much water is required for the particular mix We all know that the water-cement ratio will directly affect the strength of concrete

Water reduction helps to achieve high density mixtures, since water is the component with the lowest specific gravity Thus, the use of superplasticizers helps to obtain workable concrete with low water-cement ratio (w/c) and high density

Apr 06, 2019· Water Cement (W/C) ratio is a ratio between water weight and cement weight in a concrete mix It has a high effect on the strength and workability of concrete So, in this article, we’ll briefly discuss the calculation, maximum and minimum value of the water-cement ratio for M10, M15, M20, and M25, etc

Factors affecting the workability of concrete are materials such as water content, cement concrete, sand and aggregate properties such as size, shape, grading, mix design ratio and use of admixtur Each and every process and materials involved in concrete mixing affects the workability of concrete .

Sep 11, 2017· In this article Learn : Water cement ratio and slump test Water cement ratio : It is the ratio of water and cement (by weight or by volume) used in the preparation of concrete The quantity of water used in mixing concrete is very important If the percentage of water used is less then there shall not be sufficient quantity of water to hydrate cement
