Mar 15, 2017 Specimens without the mineral additive had the lowest strength value. It was found that aluminosilicate additive increased the compressive strength 8.19% after 6 months of curing. The analysis of results revealed that higher content of mineral additives increase the compressive strength of concrete after 6 months of curing

Addition of appropriate additives increases the strength to an optimum level. The study implies that that a peak value of compressive strength is attained when the super-plasticizer is applied as additive at a quantity of 1.45-1.48% by weight of the concrete mass. The pattern of variation of compressive strength and its relative increase with

May 28, 2014 Concrete is a composite construction material made primarily of aggregate, cement, and water. Fresh concrete must have certain features. These are shown in durability, workability, compressive strength, flexural strength, shrinkage, impact resistance, wear, and so forth. In this study, compressive strength, erosion, and attrition behavior of concrete with silica fume additive

Precast manufacturers are starting to increase the compressive strength up to 6,000 psi and even beyond. This increases the durability of the concrete while also decreasing production times. Some are even using chemical additives and steam to get up to two batches per mold per day. If you are ready to install a precast concrete wall or fence of

Mar 03, 2021 Hence the need to perform concrete testing on-site during a pour. It is estimated that concrete reaches 75% of this 28-day compressive strength in 7 days, and its strength will remain stable or even increase over time. Over time, the Concrete’s compressive strength can continue to increase due to a chemical reaction called hydration

Oct 10, 2018 Results showed that overall, by increasing the amount of additives in the porous concrete samples, the compressive strength was increased too. According to Fig. 3, coefficient of determination between the value of compressive strength and additives (talc and quartz) was 0.92 and 0.95, respectively. These relationships are meaningful

Concrete has a high, compressive strength meaning it can withstand vertical forces. However, concrete is a very brittle substance and possess a low tensile strength or resistance to horizontal forces such as expansion or contraction. To increase tensile strength, concrete can be reinforced with Fibermesh or rebar
