Jul 13, 2020 In the present contribution, the water-cement-density ratio law for the standard curing 28-day compressive strength of cement-based materials including grout, normal concrete, ceramsite concrete, and foamed concrete is proposed. The standard curing 28-day compressive strength of different grouts, normal concrete, ceramsite concrete, and foamed concrete was tested.

May 27, 2021 Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes 28 days. Marginal variations in water to cement ratio, ingredient proportioning, increase in a slump, etc impacts the desired concrete strength which in turn affects the strength and stability of structures.

Where strength is the critical design criteria, the water cement ratio in the concrete mix should be specified to ensure that the concrete reaches the required compressive and flexural strengths. Where durability is the critical criteria, the water cement ratio can be specified based on the permeability requirements as shown in the water cement ...

May 01, 2009 The concrete mixture parameters were three different water–cement ratios (0.3, 0.4, and 0.5), three different cement dosages (350, 400, and 450 kg/m 3) and four partial slag replacement ratios (20%, 40%, 60%, and 80%). Compressive strengths of moist cured specimens (22 2 C) were measured at 3, 7, 28, 90, and 360 days. ANN model is ...

For water/cement 50r ratio less than 0.4 the use of crushed aggregate has been found to give higher strength more than 38% than with the use of natural gravel. 3. Richness of the Mix: For a particular workability, higher the cement content, lesser the amount of water required, resulting in higher strength. The richness of mix is useful upto a ...

May 25, 2015 Summary. Experiments have been made on concretes with varying aggregate/cement and water/cement ratios, with the main object of ascertaining the effects of changes in age and water/cement ratio upon the relation between ultrasonic pulse velocity and the compressive strength of concrete.

However, concrete cubes obtained from fresh water gained appreciable strength with age. With the result of this research, it is recommended that fresh water and water without obvious concrete- inimical substances are used in concrete batching.
