Different Types of Concrete Grades and their uses

Concrete mixes are defined in ascending numbers of 5, starting at 10, and show the compressive strength of the concrete after 28 days. For instance, C10 has the strength of 10 newtons, C15 has the strength of 15 newtons, C20 has 20 newtons strength and so on. Get price

Concrete mix ratio?

2019/9/3The plans that were passed by your Building Control Dept would have specified the foundation concrete. If you use ready-mix you specify a grade which would normally be C15 which is between 1:3:6 and 1:2:4(C20) but certainly not 1:1.5:3(C25), as you say wickes recommend. recommend. Get price

Concrete that very likely would pass inspection

2014/6/20I think C25 would gaurantee concrete itself not failing insection. More likely than C15 or C20. My, somewhat uneducated answer then, is that C25 mix is the most likely to pass inspection considering grades C15, C20 and C25. You do not need to consider above Get price

Screed Concrete

2019/12/13Grade of the screed concrete could be C15 or C20 mainly. Further, if no screed is laid, water in the concrete will absorbed by soil before it gets harden. This will create honeycombs or dry surfaces with more porosity that could allow water to penetrate up to the reinforcement. Get price

Experimental Study on the Compressive Strength of Big

An experimental study of C20, C25, C30, C40, and C50 big mobility concrete cubes that came from laboratory and construction site was completed. Nondestructive testing (NDT) was carried out using impact rebound hammer (IRH) techniques to establish a correlation between the compressive strengths and the rebound number. The local curve for measuring strength of the regression method is set up Get price

Conventional grade C20, C25 and C30 concrete mix ratio

2018/1/17The strength of concrete is divided into twelve grades, such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60 and so on. The concrete mix ratio refers to the proportion of the components in concrete (cement, water, sand, and stone). Get price

conventional grade

The strength of concrete is divided into twelve grades such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55 and C60. Concrete mix ratios are expressed in two ways: one is expressed in materials used per cubic meter of concrete (Water: Cement: Sand: Gravel), and the other is expressed as a ratio of various materials. for example, C:S:G = 1:2.3:4.2, and W/C = 0.6.
