Mixture Optimization of Green Reactive Powder Concrete with …

Mixture Optimization Of Green Reactive Powder Concrete With …

recycled powder (rp), generated from construction waste, can be used as supplementary cementitious material. it is promising to use recycled powder in reactive powder concrete (rpc) to develop a green high-performance mixture with reduced cost. based on previous study, different mixtures were designed and a comprehensive experimental program was,utilization of recycled concrete aggregates in stone mastic …,recent studies indicated that recycled concrete aggregate (rca) materials have been used successfully in new concrete constructions as structural or nonstructural purposes [4–8]. also, several studies have been carried out on the possibility of using rca in base and subbase either as unbound materials or bitumen-treated or cement-treated granular materials [ 9 – 11 ].

Eco-Friendly Alternatives To Traditional Concrete | Specify Concrete

Eco-Friendly Alternatives To Traditional Concrete | Specify Concrete

ashcrete is a substitute for traditional concrete that heavily utilizes recycled fly ash. fly ash is mixed with lime and water to make it strong and durable, similar to conventional cement. use of fly ash in ashcrete makes it an environment friendly alternative, since it can replace cement which in turn leads to reduced co2 emissions.,infrastructure construction with recycled materials,advantages of using flyash in concrete: cement production units emit around 0.88 ton of co 2 per ton of clinker produced. fly ash replacement in cement production reduces carbon dioxide emission to that extent. utilization of fly ash as a part replacement of cement or as a mineral admixture in concrete solves its disposal problem to some extent.

Green Concrete: Its Application, Advantages & Disadvantages

Green Concrete: Its Application, Advantages & Disadvantages

to sum up, in the manufacturing of green concrete, waste materials are used as partial or full replacement of natural materials like sand or aggregates. reuse of such materials gives numerous advantages over conventional concrete, such as, it reduces the extra load on the landfills for waste material disposal.,the use of recycled material in concrete -,the mix can also be affected by the shrinkage of the concrete, the use of recycled concrete has its advantages as it is cost effective if the material i.e. rubble is sourced from a nearby demolition and it doesn’t need to be transported far for processing or reuse.

Infrastructure Construction with Recycled Materials

Infrastructure Construction With Recycled Materials

with the concept of its use in making bricks and highway pavement, the recycled aggregate concrete was used for casting curve, chute drain, median drain & side drain components of highways. a concrete mix with recycled aggregate was designed in the grade of m 25 with cement content of 300 kg/cum. chute drain components were pre-cast with this concrete mix.,mechanical properties of recycled aggregates concrete,recycled concrete aggregates contain not only the original aggregates, but also hydrated cement paste. this paste reduces the specific gravity and increases the porosity compared to similar virgin aggregates. higher porosity of rca leads to a higher absorption. 1.3 research objectives.
