“…By adding small quantities of CaCO3 partially increase in the strength was seen. Sui et al (2018) tested reactive powder concrete with calcium carbonate concrete waste powder instead of silica fume. It was seen that strength of this concrete was not obviously reduced.…”

Limestone has been commonly used in concrete for several decades. Moreover, calcium carbonate was used as a portion of cement content. Therefore cuttlebone powder, which is composed of a naturally occurring crystal form of calcium carbonate named aragonite, was used in concrete as a substitution of a portion of cement content in this research program for the first time. It led to the production of green concrete which is a type of concrete causes less harm to environment. 3, 5 and 7 percent of cement were substituted with cuttlebone powder. For this purpose, 4 concrete mix designs included 36 cubes, 4 cylinders and 4 prisms were casted. Results showed that weight of the specimens with cuttlebone powder was lower than control specimen. Moreover, by adding cuttlebone powder to concrete, slump increased. Although compressive and tensile strengths of the specimens with cuttlebone powder were lower than control specimen, but the specimen with 3% cuttlebone powder had adequate strength. Besides, three-point flexural strength of the concrete with 3% cuttlebone powder was higher than control specimen. It seems that by reducing water content of the specimen with cuttlebone powder to have similar slump to the control specimen, better performance of concrete can be achieved. So, this natural material can be used instead of a portion of cement to produce green concrete.

The aim of current experimental research is to examine the performance of the Reactive Powder Concrete modified by Pulverized Local Wastes materials. In this research, Reactive Powder Concrete was adapted by using local wastes (finely crushed ceramic tiles wastes) with Portland cement, silica fume, water, and chemical admixture through partially replacement of fine sand for sustainable practice in construction. This study exploited normal curing process at ambient temperatures as an alternative of higher temperatures steam curing for sustainability of construction works. To assess the behavior of the modified Sustainable Reactive Powder Concrete mixes, splitting and compressive strengths of Reactive Powder Concrete were inspected experimentally, and then associated with traditional Reactive Powder Concrete mix (the control mix). Furthermore, the hardened density of the modified Sustainable Reactive Powder Concrete was checked. The inquiry results directed that substituting the fine sand partially by Pulverized Local Wastes (finely crushed ceramic tiles wastes) is an adequate method for construction applications. Consequently, the compressive strength and spilling strength of modified Sustainable Reactive Powder were maintained by using 10 % of finely crushed ceramic tiles wastes. Results illustrate that Reactive Powder Concrete have an insignificant strength loss with 10 % sand replacement for compressive strength and splitting strength. The reduction percent in the compressive strength and splitting strength at 28 days are 12.37% and 8.55%, respectively, linked with related control mix.
