“…For example, the fresh density of MFKR0 was 2332 kg/m 3 which decreased to 2280 kg/m 3 when all the natural coarse aggregates were replaced with the RCA. This trend of decrease in the fresh density with increasing RCA replacement level is in agreement with results reported in the literature (Kou and Poon 2009). Measured fresh properties of the SCCs are compiled in Table 4 and they were noted to be in compliance with the requirements of EFNARC (EFNARC 2002).…”

“…In both these concrete grades, compressive strength decreased by not more than 5% for complete replacement of the NCAs with the RCAs. Various authors (Senas et al 2016;Guneyisi et al 2016b;Revathi et al 2013;Kou and Poon 2009) have stated that behaviour of fresh self-compacting concrete is significantly affected by the use of recycled aggregates. According to Guneyisi et al (2016b), "the selfcompactability characteristics of the concrete are remarkably improved by the replacement levels of CRCA and FRCA used in the SCC mixtures".…”

“…Extensive research have been conducted to evaluate the properties of concrete containing recycled coarse aggregates but very limited research have been conducted to examine the effect of recycled fine aggregate (RFA) on properties of concrete [3][4][5][6]. Khatib [6] reported only 10% reduction in 28-day compressive strength of concrete containing 100% RFA, while Evangelista [4] observed negligible effect on the compressive strength of concrete containing RFA of 30% or less.…”

Synopsis: This paper reports the properties of concrete containing recycled fine aggregate (RFA) and fly ash (FA) obtained from local source in Perth, Western Australia (WA). This study is consisted of two parts. In the first part, the properties of concrete containing 25, 50, 75 and 100% (by wt.) replacement of natural fine aggregate (NFA) with RFA are considered. In the second part, the effect of class F fly ash as partial replacement of cement on the properties of recycled concretes containing 25% and 50% RFA are evaluated. The fly ash is used as 30% and 40% replacement of cement. The properties of concrete evaluated are the compressive strength, indirect tensile strength, flexural strength and water absorption. All properties are measured at 7, 28 and 56 days. The results show that, better compressive, tensile and flexural strength of concrete can be obtained in recycled aggregate concretes containing upto 50% RFA as partial replacement of NFA. However, in the case of recycled aggregate concretes containing 30% and 40% fly ash the compressive strength is increase at 56 days and both compressive strength and tensile strengths are decreased at early ages. The flexural strength is increased in recycled aggregate concrete containing fly ash. It is observed that the water absorption is increased as RFA content increased. It is also observed that the water absorption is decreased significantly in recycled aggregate concretes containing fly ash at 56 days.

This paper presents the results of experimental investigations on mechanical properties of self compacting concrete made with local materials. The used materials were cement, aggregate and super plasticizer. Limestone powder, silica fume and blast furnace slag have been used as adjuvant in self compacting concrete (SCC). Self compacting concrete properties in fresh and hardened state are characterized and analyzed. The test results indicate the possibility to manufacture SCC with good rheological and mechanical properties using local materials.
