A Review on Experimental Investigation of Fibre Reinforced Metakaolin-Based Geopolymer Concrete
Abstract: The development of new binders, as an alternative to Portland cement (PC), by alkaline activation, is a current researcher’s interest. As Concrete is the most commonly used material for construction. The worldwide production of cement has greatly increased after 1990. Production of cement results in a lot of environmental pollution as it involves the emission of CO2 gas. There are many ways to which we can reduce environmental pollution (carbon …

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 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 …

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 …
