### DOE Methods of Concrete Mix Design Concrete

Find out the water/cement ratio for targeted strength 45 MPa. (a) For finding out the w/c ratio, refer to table 20.46. From this table for ordinary port-land cement and uncrushed 20 mm aggregate the 28 days strength is 42 MPa. (b) From Fig. 20.12 find the point of inter section of 42 MPa at 0.5 water/cement ratio. Through this point draw a

Mix design refers to the method for finding out the proper quality materials and their relevant ratios which can be used to form concrete with optimal properties ranging from applicability, strength, setting time and stability. To form nominal mix concrete, cement, sand and aggregate are roughly proportioned. The purpose of nominal mix concrete is to gain target compressive strength. Mix ratio

The ratio of fine aggregate to coarse aggregate to be used in concrete is 12, which means that for every 1 part of sand we have to take 2 part of gravel. Hence we have to divide the Total Aggregate into 3 parts and take 1 part as sand and 2 parts as coarse aggregate. Lets calculate weight of sand and gravel needed for M15 Grade concrete. Weight of Sand required per bag of cement = (330/3) x 1

Concrete is made from different proportions of cement, fine aggregate (sand), coarse aggregate, and water. Cement usually comes in 94 lb sacks, water is measured by gallons (volume), and coarse and fine aggregate by weight. These are all over the place. There are two main methods of measuring concrete ingredients, the Absolute Volume Method, and a method using Proportion ratio of components
