This paper present the experimental result carried out to determine workability and compressive strength of concrete at different replacement of PPC. M 25 grade of concrete 1 1.53 3 at w c of 0.42 was designed as per IS 10262 2009. Result shows that PPC can be replaced up to 20 by fly ash without compromising compressive strength of concrete.

Get Price24.08.2020· The compressive strength of concrete is its ability to withstand against external compressive loads. It depends upon the constituents used in concrete and conditions in which concrete is mixed, caste in specimens and curing conditions. It is not an intrinsic property of concrete. Compressive strength has great significance in designing the reinforced concrete structures. Other

If you were to actually break 100 cylinders of same strength concrete though, you would get a decent amount of variability. This variability comes from different aggregate size, different w/c ratios, and other parameters. Since you have high material variability, and a small localized load application; the available

Get PriceThe strength of concrete generally represents the compressive strength of concrete, as concrete has maximum compressive strength and is its unique feature. Therefore, in concrete the characteristic strength of concrete literally means Characteristic compressive strength unlike in other materials like steel or wood, etc. so most of the design of the concrete structure is done by adopting
Get PriceCompressive strength as a concrete property depends on several factors related to the quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common].
