WebOct 3, 2024 · The main objective of this work is to investigate the mechanical characteristics of foamed concrete with varying density (400–1400 kg/m 3 ). A series of tests was performed to examine compressive strength, elastic modulus, flexural strength, and material degradation characteristics after freeze-thaw cycles. 2. Experimental Program 2.1. Concrete has relatively high compressive strength (resists breaking, when squeezed), but significantly lower tensile strength (vulnerable to breaking, when pulled apart). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by … See more Concrete has relatively high compressive strength, but significantly lower tensile strength. As a result, without compensating, concrete would almost always fail from tensile stresses ( Reinforced concrete is … See more The ultimate strength of concrete is influenced by the water-cementitious ratio (w/cm), the design constituents, and the mixing, placement and curing methods employed. All things being equal, concrete with a lower water-cement (cementitious) ratio makes a … See more As concrete matures it continues to shrink, due to the ongoing reaction taking place in the material, although the rate of shrinkage falls … See more Portland cement concrete holds water. However, some types of concrete (like Pervious concrete) allow water to pass, hereby being perfect alternatives to Macadam roads, as they do not need to be fitted with storm drains.
