Concrete slump test

Concrete SAMPLING: The first step is to take a test sample from the large batch of concrete. This should be done as soon as discharge of the concrete commences. The sample should be representative of the concrete supplied. The sample is taken in one of two ways: 1. For purposes of accepting or rejecting the load: Sampling after 0.2 m3 of the load has been poured. 2. For routine quality checks: Sampling from three places in the load. Concrete Slump Test: This test is performed to check the consistency

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement, but sometimes binders such as asphalt or gypsum are used, in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement, water, sand, and coarse aggregate) but also, to a great

assess the influence of addition of steel fibers to Self Compacting Concrete (SCC). The objective was to assess and compare the various mechanical properties of self compacting concrete with and without steel fibers. Various percentage of steel fibers viz. 0%, 1%, 3%, 5% and 7% were added. The effect on the properties of the fresh concrete was studied by means of slump test, V-funnel test, L box test etc. The properties of hardened concrete were investigated by assessing the compressive strength and split

Infrastructure development across the world created demand for construction materials. Concrete is the most important construction material. Concrete is a mixture of various ingredients like aggregates, water and admixture. Aggregate form is the major part of concrete among the entire ingredients used in concrete. The use of normal weight of aggregate such as gravel and granite probably reduces the natural stone deposits and it cause effect on environment

SELF COMPACTING CONCRETE Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. The highly fluid nature of SCC makes it suitable for placing in difficult condition & in selections with congested reinforcement. Use of SCC can help in hearing related damages on the worksite that are induced by vibration of concrete, another advantages of SCC is that the time required to place large section in consider ability reduced. When the construction

2.3.4.3 Nanomaterials Nanoparticles (NPs) have recently received special attention because of their better performance when compared with traditional mineral additions. The addition of NPs can improve the properties of concrete due to the effect that the increased surface area has on reactivity and through filling the NPs of the cement paste. Some of these nano particles include Silicon dioxide, Copper oxide, Zinc peroxide, Titanium dioxide. The addition of silicon dioxide or titanium dioxide NPs
