An Investigation on Aggregate Distribution in Concrete
Abstract: Falling behavior is generally studied by mathematicians. The first study is conducted by Comte de Buffon with name “Falling needles experiment” and is widely known. Buffon researched the falling needle behavior finding the fall of needles in relation with Pi. However, although aggregates are fallen to the mould in cement paste, falling behaviour of concrete is rarely studied considering the statistical parameters of the fall.Accordingly, an experimental study is conducted …

Optimum Weight Design of a Singly Reinforced Rectangular Concrete Beam
Abstract: In this paper, the results of the optimum weight design of a simply supported singly reinforced concrete rectangular beam under uniform loading with respect to bending moment, steel ratio and design variable constraints are discussed. The design constraints were derived based on BS 8110, Part 1, 1997 design rules. The values of the design variables that optimized the self-weight of the beam subject to the constraints considered were obtained using …

Effect of RHA on Strength of M20 Concrete under both Acidic and Non-acidic Medium by Using Ultrasonic Pulse Velocity Test
Abstract: This work investigates the effects of adding rice husk ash (RHA) on strength of M20 cement concrete under both acidic and non-acidic medium by using NDT i.e., Ultrasonic Pulse Velocity Test. M20 strength concrete was produced using locally available materials. The rice husk ash (RHA) passing 200 micron and 325-micron sieves taken as a 0% - 20% weight of cement & replacement of cement has been done. The RHA effect …

Scrap Steel Fiber Reinforce Concrete
Abstract: The research mentioned on this paper turned into finished to look at the feasibility of the usage of metal scrap received from lathe system in fiber bolstered concrete via way of means of checking the compressive strength, and flexural strength of M20 concrete and consequently optimizing the fiber proportions. In this look at, a contrast has been made among undeniable cement concrete and metal scrap fiber bolstered concrete (SSFRC). The …

Impact of Additives on the Split Tensile Strength of Roller Compacted Concrete
Abstract: Additives are implemented as partial replacement of Portland cement in concrete to enhance the required physical properties. In the present investigation, roller compacted concrete slab samples were prepared using gap and dense aggregate gradation. Three percentages of Portland cement were adopted, (16, 12, and 10) % by weight of aggregates. Three types of additives, (hydrated lime, fly ash, and fumed silica) were implemented as partial substitute of Portland cement. Core …
