“…However, the mean relationship proposed by CEB-FIP model generally provided higher tensile strength value. This finding may be confirmed by the results of Parra et al (2011), reported that at more advanced ages (28 and 90 days), there is a clearly higher tensile strength in normal vibration concrete than in SCC for the same compressive strength.…”

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.

“…HPFGC proportioned with 20 % RHA had lower splitting tensile strength with respect to the control sample. It is well documented that splitting tensile strength is mainly governed by aggregate-paste bond (Nazari and Riahi 2011;Parra et al 2011). RHA incorporation refined the transition zone between cement matrix and aggregate, and reduced the amount of large calcium hydroxide crystals and ettringite due to additional C-S-H phases generated from pozzolanic reaction, as mentioned in the previous section.…”

Rice husk ash (RHA) is classified as a highly reactive pozzolan. It has a very high silica content similar to that of silica fume (SF). Using less-expensive and locally available RHA as a mineral admixture in concrete brings ample benefits to the costs, the technical properties of concrete as well as to the environment. An experimental study of the effect of RHA blending on workability, strength and durability of high performance fine-grained concrete (HPFGC) is presented. The results show that the addition of RHA to HPFGC improved significantly compressive strength, splitting tensile strength and chloride penetration resistance. Interestingly, the ratio of compressive strength to splitting tensile strength of HPFGC was lower than that of ordinary concrete, especially for the concrete made with 20 % RHA. Compressive strength and splitting tensile strength of HPFGC containing RHA was similar and slightly higher, respectively, than for HPFGC containing SF. Chloride penetration resistance of HPFGC containing 10-15 % RHA was comparable with that of HPFGC containing 10 % SF.

“…Most published articles acknowledged that for a selected compressive strength value, SCC could reach a tensile strength value which is slightly smaller than of NVC [14][15][16][17][18]. For instance, Parra et al [14] registered lower values of splitting tensile strength of SCC made with limestone powder (LP) filler than that of NVC, however, Felekoglu et al [17] showed that higher splitting tensile strength values were obtained in SCC rather than NVC.…”

self-compacting concrete (scc) is becoming more popular in terms of application and innovation in the building industry. Durable concrete structures can be established when scc is used with the proper mix design and selection of materials. the amount and type of filler or supplementary cementitious materilas (scms) are among the most important parameters affecting the fresh and hardened properties of scc. mainly, scms improve the hydration of cement due to their physical characteristics and chemical compositions, thus a more sustainable and eco-friendly scc product could be achieved by the substitution of cement clinker by scms. the aim of this study was to evaluate the effect of total powder content, cement content and scms type on the fresh and hardened properties of scc. the compressive strength, splitting tensile strength, modulus of elasticity and total porosity properties were the experimental tests carried out in this investigation. the finding of this study showed that the compressive strength of scc with metakaolin (mk) gives higher values, as compared to mixtures with silica fume (sF), at the age of 400 days. mk and sF showed a negligible effect on the splitting tensile strength and modulus of elasticity, as compared to the reference mixtures. total porosity test results were lower with the increase of total powder content and by the addition of scms. keywords: self-compacting concrete, mechanical properties, sustainability, metakaolin, silica fume
