“…The use of such powders provides greater cohesiveness by improving the grain-size distribution and particle packing. Moreover, their high pozzolanic activity leads to a further particle packing enhancement that is achieved by the pozzolanic products and acts complementary to the physical action (Sfikas et al 2014).…”

The successful completion of the present research would be achieved using ground waste glass (GWG) microparticles in self-consolidating concrete (SCC). Here, the influences of GWG microparticles as cementing material on mechanical and durability response properties of SCC are investigated. The aim of this study is to investigate the hardened mechanical properties, percentage of water absorption, free drying shrinkage, unit weight and Alkali Silica Reaction (ASR) of binary blended concrete with partial replacement of cement by 5, 10, 15, 20, 25 and 30 wt% of GWG microparticles. Besides, slump flow, V-funnel, L-box, J-ring, GTM screen stability, visual stability index (VSI), setting time and air content tests were also performed as workability of fresh concrete indicators. The results show that the workability of fresh concrete was increased by increasing the content of GWG microparticles. The results showed that using GWG microparticles up to maximum replacement of 15 % produces concrete with improved hardened strengths. From the results, when the amount of GWG increased there was a gradual decrease in ASR expansion. Results showed that it is possible to successfully produce SCC with GWG as cementing material in terms of workability, durability and hardened properties.

“…the workability, the viscosity and the passing ability, were assessed by the Slump-flow, the V-Funnel and the LBox tests, respectively, and classified in accordance with the relevant European Standards [36][37][38]. The detailed results and discussion regarding the fresh properties have already been published as part of another study on the fresh and mechanical properties of the same mixtures [8] and only the classification is reported here (Table 5), for reasons of completeness.…”

“…The aim of the present study, which is part of a wider research project on SCC incorporating mineral admixtures [8,10,[29][30][31], is to investigate the effect of mk on the durability of SCC mixtures. For this purpose, mk was used as a replacement material of either cement or limestone powder, at various percentage levels.…”

“…Durability improvement can be achieved to a great extent by the incorporation of supplementary cementitious materials (SCM) in the mixture. Due to their high pozzolanic activity and filling effect, SCMs can lead to the production of a more consistent, cohesive and dense concrete, which exhibits enhanced mechanical characteristics [3][4][5][6][7][8] and reduced permeability [3,6,[9][10][11][12]. Among other cementitious materials, such as silica fume (sf), granulate blast-furnace slag (ggbs) and (pulverized) fly ash (pfa), that are frequently used for the production of concrete, metakaolin (mk), is a material with a feasible growing implementation in the concrete industry.…”

An effort has been made to enhance the flexural fatigue lives of self compacting concrete (SCC) in which half of the natural aggregates (NA) were substituted with recycled concrete aggregates (RCA) by means of blended cements. Blended SCC mixes containing either silica fume (SF) or metakaolin (MK) along with cement, and fly ash (FA) was also adopted. Fatigue lives have been evaluated as mean value, design value life and theoretical value. The Weibull distribution parameters were utilized for the valuation of mean and design values of fatigue lives for different considered mixes. It has been observed that adding RCA in SCC causes degradation in the fatigue lives, which can be enhanced by adopting the blended mixture comprising of SF or MK, cement and FA. Both SF and MK established a promising result in improving fatigue lives. Still, the blend of MK in SCC contributed most effectively in enhancing the fatigue life of SCC comprising RCA.
