Effect of Colloidal Nanosilica on High Strength Rice Husk Ash Concrete
Abstract: Nowadays, supplementary cementitious materials (SCMs) are used in concrete because it reduces CO2 emission during. The husks, which are production of cement, reduces cement contents, improve workability, increase strength and enhance durability. Pozzolanic reaction takes place when siliceous or aluminous material comes in contact with calcium hydroxide in the presence of moisture to form compounds possessing cementitious properties approximately 50 percent cellulose, 30 percent lignin and 20 percent silica, are …

Improving Durability of Asphalt Pavement Wearing Course Submerged in Water Using Candle Wax as Water Proofing Agent: An Assessment Using RSI, FDI and SDI
Abstract: Asphalt pavements are designed and constructed to meet mostly stability and durability requirements during its design life. However, durability of asphalt pavements also heavily depends on other physical parameters as good drainage facility apart from having good material mix and structural designs. In the wake of asphalt pavements not supported by good drainage measures it is very likely that these pavements will fail sooner than later. On this basis, the …

An Experimental Study on Concrete by Replacement of Coarse Aggregate with Demolished Building Waste in Crushed Concrete
Abstract: A large amount of construction and demolition wastes are produced annually in India. These waste materials require a large place to dispose and then the disposal of wastes has become a severe problem. The continuous use of natural resources for making conventional concrete leads to the reduction in their availability and results in the increase of the cost of the coarse aggregate and fine aggregate. The possible use of recycling …

A parametric study for the behaviour of steel plate-anchor assembly embedded in concrete under cyclic loading
Abstract: Steel plate-anchor assembly embedded in concrete is a common type of connection system used for connecting structural steel members to concrete members. These assemblies are subjected to different loading cases depending on their use. Since the behaviour of such assemblies is quite complex and depends on a number of factors associated with different components, it was decided to adopt finite-element technique to obtain a reasonably accurate analytical solution for the …

An overview on the rheology of recycled aggregate concrete with the influence of chemical admixtures
Abstract: : Concrete is one of the most widely used construction material because of its property to be moulded into any kind of structure and shape due to its fluidity at early stages. The fresh properties of concrete can be characterized by its flow behaviour. Rheology is the scientific description of flow properties. Super-plasticizers and air-entrainers are some of the most used chemical admixtures that affect the rheological parameters of fresh …

Experimental Study of Mechanical Properties Geopolymer Concrete.
Abstract: This experimental study aimed to define the parameters for optimum mix design of geopolymer concrete made by partial replacement of cement. The geopolymer concrete is nothing but the formation of fly ash and alkali activators. Fly ash is the waste product from the thermal power station and may use as the pozzolanic material. But, only fly ash is may not the only replacement for the cement, for the more binding …

Mechanical Properties of sand blasting residue concrete
Abstract: Sand Blasting Residue (SBR) form chain manufacturing companies as a large massive by-product. Steel-slag hydrated matrix is made of ground granulated blast furnace slag powder & steel-making slag which is the by-product of iron manufacturing. This type of construction material is called environmental conscious material in Japan. This research presented that the strength of steel-slag hydrated matrix depends on the pH of the steel-slag hydrated matrix after mixing. Firstly, cement, …

Mechanical Behavior of Fly Ash Concrete A Critical Review
Abstract: Concrete structure is the most common all over the world. Cement is the major ingredient of concrete. Though the raw materials needed for manufacture of cement are available in most parts of the world, many countries have severe shortage of cement, although their needs are vast. The search for suitable substitute for cement, either partially or fully, has thus become a challenge for planning the development of many of the …
