Experimental study of concrete made with granite and iron powders

The key to a strong and durable concrete are the mix proportions between the various components. Less cement paste can lead to more voids, thus less strength and durability while more cement paste can lead to more shrinkage and less durability. The gradation and the ratio of fine aggregates to coarse aggregates can

In addition to these basic components, supplementary cementitious materials and chemical admixtures are often used to enhance or modify properties of the fresh or hardened concrete. Concrete Aggregate. The coarse and fine aggregates used in PCC comprise about 80 to 85 percent of the mix by mass (60 to 75 percent

Concrete Technology Civil Engineering Questions and Answers

Thumb rule for the calculation of quantity of water in Concrete is Amount of water = (5% of Fine aggregate + 30% of Cement)* Water Cement ratio. So for a concrete mix of 1:3:6, Cement per bag = 50 Kg, Fine aggregate = 3*50 = 150 Kg. So amount of water required will be W = (5% of 150 Kg + 30% of 50 Kg)* 0.6,

Feb 4, 2014 Each truck of sand from the same place at different time may not be the same and it is difficult to design mix proportion for each truck of sand and this call for a standardization of materials in Ethiopia. In my research I made concrete C25, C30 and C40 as control mix by standardizing the aggregate to the

Study on the Utilization of Paper Mill Sludge as Partial Cement

mix of paper mill sludge as cement replacement for concrete were prepared with a DoE mix design by calculating the weight of cement, sand and aggregate. The performance of each concrete specimen was compared with the strength of the control mix. As a result, when the percentage of paper mill sludge in the concrete

Calculate cement sand and aggregate Nominal Mix Concrete Civil

Following is a simple method used by engineers to calculate cement, sand and aggregate in volume(cubic metre) and in weight (kg) to produce nominal mix concrete. In nominal mix method, materials are proportioned based on prescribed proportions to attain the different grade of concrete. They are easier to practice on

aci method of concrete mix design: a parametric Semantic Scholar

The study reveals that ACI method fails to rationally predict the proportion of the ingredients when coarse aggregates of higher voids is used in making the concrete. In such cases, the amount of fine aggregate is over estimated. This over estimation leads to a higher surface area to be covered by the same amount of cement,
