الحصول على السعرThe practical best watercement ratio is from about to over A ratio of is made concrete too stiff (unless superplasticizers are used). A ratio of makes concrete wet and fairly weak concrete. Normal compressive strengths when concrete is properly cured are: w/c ratio –> 5600 psi. w/c ratio –> 2000 psi.
الحصول على السعرHigher aggregatecement ratio implies, bigger volume of concrete is involved by the aggregates subsequently less extent of cement glue. The full volume of porosity in concrete framed after the hydration would be lower for the lower volume of cement glue utilized.
الحصول على السعرIn this column, we will use the M20 grade of concrete (which Ratio is 1::3) sum of ratio become = where: 1 is Cement, is Sand, and 3 is aggregate. ( M20 grade of concrete compressive strength is 20N/mm2 after 28 days). Now we have to find out Volume of .
الحصول على السعرCoarse Aggregate = (Coarse Aggregate Part / Concrete Parts ) * Concrete Volume = (3/) * 2 = m 3 . Water Cement Ratio. According to IS 10262 (2009), Assuming WaterCement Ratio for the Concrete as Required Amount of Water = W/C Ratio X Cement Volume
الحصول على السعرSimilar method will be applicable for finding out the different grades of concrete mixes. The Concrete mix ratio for M20 grade of concrete is 1::3 1 part of cement, part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing.
الحصول على السعر· There are two main ways to design the concrete mix. Design mix method : In this method, materials are proportioned based on the procedure and rules given in IS 456 (2000) and IS 10262) code . In this method, cement, sand and aggregates are always batched in terms of weight, and concrete can be designed for different environmental conditions and different needs.

الحصول على السعر· Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard.
الحصول على السعر3) Standard Concrete Design: Standard concrete mix/ratio is based on IS Code concrete mix. It has been separated into different mix ratios of concrete quantity of cement, sand, and aggregates for different grades of concrete. The different grades of concrete are M5,, M10, M15, M20, M25.
