“…This may be caused by the interaction between FA and BFS. On the other hand, the difference of absorption capacity among cement, FA and BFS may also cause the porosity difference, since the published results already verified that the absorption capacity affects the porosity [36,37]. In this study, the effect of absorption capacity on the effective porosity was beyond the limit of this study, and further study on this point will be conducted in the future.…”

Eco-friendly pervious concretes containing fly ash (FA) and blast furnace slag (BFS) were prepared in this study. The compressive strength and hydraulic behaviors were investigated to explore the effect of replacement content of FA and BFS. Rheological tests of cementitious pastes were first conducted and the results showed that FA could increase the apparent viscosity and BFS did not change the rheology performance. Compared to traditional concretes, FA and BFS both decreased the compressive strength of pervious concrete at 28 d, while pervious concrete incorporated with FA and/or BFS presented comparable strength at 60 d. Compared to the control concrete mix, at the same replacement rate, FA changed the compressive strength more obviously than BFS. FA and BFS both decreased the effective porosity and permeability coefficient of pervious concrete. However, when the replacement rate (30%) was the same, concretes with ternary blends presented obviously larger porosity than binary blends. The relationships between porosity and permeability, and strength were also established.

To overcome the scarcity of natural resources as construction material and to reduce the hazards from industries, industrial wastes can play a very significant role. In this paper, the influence of glass powder and steel slag is reviewed. It is concluded that glass powder and steel slag can upset some portion of concrete thereby providing significant improvement in mechanical properties of concrete consequently reducing the environmental hazards from industries.

“…Moreover, the integral use of natural aggregates (fine and coarse) caused an increase of capillary water absorption of 42%. Anastasiou, et al (2014) studied the use of fine aggregates in concrete with fly ash and steel slag. The results showed that the use of fine aggregates from C&D increases concrete's porosity and reduces its durability.…”

The construction industry is searching for a more ecological material which can provide a good sustainability and also have the eco-friendly label. The quest to protect the environment has enabled researches to find alternate materials which can fit the concrete matrix to produce a concrete that can meet the demand of the construction industry. The purpose of this research is to substitute traditional materials with construction and demolition waste by keeping the same slump value and by replacing natural fine aggregates (NFA) with Construction and Demolition Waste (C&D) materials and investigate their properties on fresh and hardened concrete. To determine and compare the properties, different tests were performed to evaluate the workability, density, compressive strength, flexural strength and absorption of each concrete mix. The results demonstrated that, construction and demolition waste materials with a define slump range decreases the compressive strength and flexural strength, and the water absorption increases with increasing C&D content.
