AbstractA quaternary supplementary cementitious materials as partial replacement of ordinary Portland cement decreases CO2 emission. This paper has investigated the properties of mortars made from different quaternary blends of wood ash, steel slag powder and glass powder with ordinary Portland cement at different replacement levels of 0, 24, 25, and 30% by weight of the binder. The blended mortar mixtures tested for flow, compressive strength and density. The results showed that the flow of mortars is decreased with the combined use of steel slag powder, glass powder, and wood ash compared with control mix. Compressive strength reduced with the combination of steel slag powder, glass powder and wood ash but this reduction effects is acceptable especially at 24% replacement contain super-plasticizer compared with the ecological benefit.

AbstractConcrete is the most widely used construction material in the world. Over ten billion tons of concrete are being produced each year resulting in exhaustion of natural materials and an enormous carbon footprint. One of the primary goals of concrete technology today is to reduce the use of Portland cement and natural fine aggregates by partially replacing them with various waste materials and by-products of industrial processes. The paper summarizes the results of a study where the partial replacement of river sand and Portland cement was successfully applied using steel slag aggregate, silica fume and glass waste.

Initial Framework

The sodium silicate has activation function on the macroscopic mechanical properties and microscopic structure of the gas quenching steel slag cement. Research results show that: Under the activation of the sodium silicate, when the content of the gas quenching steel slag cement is 30% to 40%, acid Salt, Portland cement grade 42.5 can be produced. Even when the content of gas quenching steel slag is improved to 50%, slag Portland cement grade P·S·A32.5 can still be produced. Seen from the hydration products, the sodium silicate reacts with the ions in the gas quenching steel slag, on one hand, initial framework is formed to enrich the network structure; and on the other hand, in the hydration process, a large number of C-S-H gel, ettringite crystal and a small amount of Ca (OH)2 are formed, which improves the strength of cement.
