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 …

EFFECT OF FLY- ASH AND CEMENT ON EXPANSIVE SOIL FOR FLEXIBLE PAVEMENT DESIGN
Abstract: Out of the many types of soils that prevail on the Earth’s crust Expansive soils are observed to be highly problematic by nature. Particularly under conditions of loading, these soils are highly prone to fail due to shear, crushing or excessive settlement. These factors end up expansive soils as unsuitable soils for any construction. If the strength of the soil is poor, then soil stabilization is duly needed. Stabilization is …

Effects of granulated waste glass and micro steel fiber on shear strength parameters of sand
Abstract: During the construction of the various structures, soil strength plays a vital role in structural performance. Hence, soil improvement techniques are needed to improve soil strength as well. This study aimed to improve shear strength of sandy soil using Granulated waste glass (GWG) and Micro steel fiber (MSF). In order to apply this idea, there have been taken two kinds of sandy soil such as fine sand (locally available in …
