Study of Durability Properties of Bagasse Ash Concrete and Its Behaviour when Exposed to Elevated Temperatures
Abstract: The major driver for the economic growth and social progress of any country is its construction sector. In India, it is estimated that construction contributes 8% to 9% to GDP and this share is likely to increase in coming years. High-performance concrete made from ordinary Portland cement (OPC) and various supplementary cementitious materials (SCM) are alarmingly finding their use in construction worldwide. Bagasse ash (BA), one such SCM, the agro-industrial …

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 …

PREDICTION OF RECYCLED CONCRETE AGGREGATE SELF COMPACTING CONCRETE COMPRESSIVE STRENGTH USING MATHEMATICAL MODEL
Abstract: Sustainable Development aims at improving the standard of life without compromising the environmental qualities and for future needs. These objectives can be achieved through recycling of construction/demolished waste. In Past, land filling of Construction and Demolished waste materials was the general solution. As raw Construction Material Charges have risen dramatically, we have to look for alternative solutions and methods, such as recycling of demolished waste. Recycled Aggregate Concrete not only …

Cost Impact of Structural Irregularities
Abstract: Since absolute regularity is an idealisation that seldom exists, building structures are typically irregular. Building irregularities are unavoidable because of the many practical and aesthetic benefits. The performance of buildings subjected to earthquake pressures has revealed that asymmetric and irregular constructions produce more severe damage than regular structures, and the collapse of these structures may be blamed for the majority of human fatalities. Vertical mass inconsistency is commonly due to …

Simulation of delay variation at uncontrolled intersections for mixed traffic conditions
Abstract: Mixed traffic is composed of different vehicle types with varying geometric and acceleration characteristics. Capacity and delay are the two parameters mainly used to measure the effectiveness of uncontrolled intersections. The variation in the lengths and widths of a vehicle type also has an effect on the capacity and delay. Three intersections and three vehicle types are considered for the study. Also, different vehicle compositions scenarios (C1 to C11) were …
