Abstract Due to significant industrialization, many countries have adopted the practice of industrial symbiosis, which involves utilizing waste produced by one industry as a resource for another industry. The utilization spent foundry sand (SFS), is derived from metal casting industry, poses risk both environment and living organisms result existence inorganic organic substances. Nevertheless, ...

In this study, Self-Compacting Concrete (SSC) was produced by using Fly Ash (FA) and Marble Powder (MP), which reduces the amount of cement, causes less damage to environment has some superior properties compared normal concrete. The changes in physical mechanical SSCs with increasing age were investigated. CEM I 42.5 R cement used as a binder production SSC. It FA MP at rates 10%, 20% 30% weig...

Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...

In this study two series of self compacting concrete mixtures were prepared with 100% coarse recycled concrete aggregates and different percentages of 0%, 20%, 40%, 60%, 80% and 100% fine recycled concrete aggregates. In series I and II the water to binder ratios were 0.50 and 0.45, respectively. The cement content was kept 350 3 m kg for those mixtures that don't have any Nano-Silica. To impro...

In order to comply with current trends concerning sustainability, saving of primary materials and energy savings, this paper addresses Eco-concrete. The major focus thereby is on the increased efficiency of cement use. Applying a new mix design method for concrete, cement contents can be decreased and partially be substituted by other fine powders, preferentially by waste powders which have no ...
