Physical and Mechanical Properties of Recycled Concrete

conventional crushed-stone base material by as much as 30%.(5) Despite the increased acceptance of recycled base materials, research concerning the mechanical properties and durability of such materials has been lacking. (3, 6) The most widely used recycled materials are recycled asphalt pavement (RAP) and recycled concrete aggregate (RCA).

Experimental studies for determining the mechanical and the physical properties of the recycled aggregate concrete (RAC) with and without silica fume (SF) is inspired by the Urban Renewal Law which regulates circumstance of existing structures in Turkey.

Concrete is the most widely used construction material in the world. There is a concern to more understanding and to improve its properties. Using waste and recycled materials in concrete mixes becoming increasingly important to manage and treat both the solid waste generated by industry and municipal waste.

The objective of this research is to study the physical and mechanical properties of mortar and concrete with addition of nano materials such as nano-silica. The addition of nano-silica will be in the range of 0.6% for partial replacement of cement by weight.

In this study, recycled aggregate concrete (RAC) modified with polypropylene fiber (PP) and air-entraining agent (AGA) was prepared, and the effects of PP and AGA on the static (compressive strength, Young's modulus, and splitting tensile strength) and dynamic properties (dynamic modulus of elasticity and damping ratio) of RAC were investigated.

Full Article. Physical and Mechanical Properties of Recycled Polypropylene Composites Reinforced with Rice Straw Lignin. Myrtha Karina, a, * Anung Syampurwadi, a Rahmat Satoto, a Yuyun Irmawati, b and Tita Puspitasari c Recycled polypropylene (RPP) and lignin represent by-products produced in enormous amounts worldwide that remain underutilized.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Fiber reinforcement can effectively improve the mechanical properties of concrete. Utilization of recycled fibers from post-consumer and industrial waste offer some benefits such as waste reduction and resource conservation and also low-cost materials and reduced need for landfilling.

Evaluation of the physical-mechanical properties of cement-lime based masonry mortars produced with mixed recycled aggregates • 3 Materiales de Construcción 70 (337), January-March 2020, e210.

Waste concrete is the most predominant constituent material among construction and demolition waste. Current waste concrete recycling is limited to the use of recycled concrete aggregates as a road-base material and less as aggregates in new concrete mixes. Further, the production of recycled concrete aggregates results in the generation of a high amount of fines, consisting mainly of cement

Physical mechanical and thermal properties of Crushed . Physical mechanical and thermal properties of Crushed Sand Concrete containing Rubber Waste. Chat Online; Elastic and Mechanical Properties of Dune Sand . The same model is used to describe the velocity versus stress behavior. These results and theory constitute a new installment into the

The study reports results of tests, using only natural aggregates, of a control concrete and nine recycled aggregate concretes. The recycled aggregates were classified according to measured specific gravity and water absorption into three different types, namely: RS II for recycled fine aggregate having 2.36 specific gravity and 5.4% water absorption; RG III for recycled coarse aggregate
