Reinforced concrete elements were casted using both saline and fresh water using a mix ratio of 1 2 4 for experiment. Compressive strength is observed for 120 days. The strength was estimated of fresh water sample was 13.08N/mm2 and 12.10N/mm2 for saline water sample on 14th day whereas strength was observed 13.98 N/mm2 for saline water and.

Chat Online### Minimum and Maximum Reinforcement Ratio in Different

Maximum Reinforcement Ratio in Beams The maximum reinforcement ratio for beams is provided to prevent concrete crushing which is an undesired mode of failure and prevented by the ACI code. It also avoids the use of excessive steel area that does not offer real benefits. Therefore it helps to bring economy in the design of concrete beams.

Water-Cement RatioThe water-cement ratio is one of the most important factors of a high strength concrete mix design. A lower water-cement ratio will generally lead to a higher compressive strength of the concrete as this will decrease the amount of free water in the mix after hydration and therefore reduce the volume of capillary pores in the hardened concrete matrix.

Chat Online### Effect of GFRP Reinforcement Ratio on the Strength and

All the columns failed in a compression failure mode due to concrete crushing. The GFRP bars developed higher tensile strains in the HSC due to the axial–flexural load compared to columns made with normal-strength concrete (NSC). A minimum reinforcement ratio of 1 in the case of HSC proved practical.

Chat Online### what is crushing strength of reinforced concrete ratio

crushing strength of concrete psi. In very highstrength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high watercement ratio) the crushing strength of the aggregates is not so significant.
