Review on the Application of Supplementary Cementitious Materials in Self-Compacting Concrete

Abstract

For the sustainable development of construction materials, supplementary cementitious materials (SCMs) are commonly added to self-compacting concrete (SCC). This paper reviewed the application techniques and hydration mechanisms of SCMs in SCC. The impacts of SCMs on the microstructure and performance of SCC were also discussed. SCMs are used as a powder material to produce SCC by replacing 10% to 50% of cement. Hydration mechanisms include the pozzolanic reaction, alkaline activation, and adsorption effect. Moreover, the filling effect and dilution effect of some SCMs can refine the pore structure and decrease the temperature rise of concrete, respectively. Specifically, the spherical particles of fly ash can improve the fluidity of SCC, and the aluminum-containing mineral phase can enhance the resistance to chloride ion penetration. Silica fume will increase the water demand of the paste and promote its strength development (a replacement of 10% results in a 20% increase at 28 days). Ground-granulated blast furnace slag may reduce the early strength of SCC. The adsorption of Ca2+ by CaCO3 in limestone powder can accelerate the hydration of cement and promote its strength development.

Rheological and Durability Properties of Self-Compacting Concrete Produced Using Marble Dust and Blast Furnace Slag

“…According to this case, sustainable and greener production of construction technologies and eco-friendly evaluation of industrial by-products are current issues [ 35 ]. There have been lots of studies about the usage of industrial by-products as a replacement material against cement for the production of SCC [ 36 , 37 , 38 , 39 , 40 ]. This study is focused on the fine aggregate replacement effect on the fresh and hardened properties of SCC mixtures.…”

Development of Eco-friendly Self-compacting Concrete Using Fly Ash and Waste Polyethylene Terephthalate Bottle Fiber

“…The price of Portland cement is relatively higher than other required concrete materials. Therefore, it is necessary to look for potential substitute materials as alternatives that should be environmentally friendly and vastly available at an affordable price [7][8][9][10][11]. Previous researchers have attempted to utilize various waste materials in SCC mixtures that are more environmentally friendly as Supplementary Cement Materials (SCMs).…”

Residual Compressive Behavior of Self-Compacting Concrete after High Temperature Exposure—Influence of Binder Materials

“…Compared to normal vibrated concrete, self-compacting concrete (SCC) contains a much higher amount/volume of fine particles (≤0.125 mm) needed to achieve mix stability or cohesion. A high percentage of fine particles in SCC is usually achieved by using mineral additives (pozzolanic and non-pozzolanic) such as fly ash, slag, silica fume, limestone, metakaolin, etc., since the use of cement alone as fines results in high production costs [ 7 , 8 , 9 ]. While the addition of mineral additives usually results in high quality and dense microstructure, which has a positive effect on mechanical properties and durability, this compact microstructure results in adverse effects in the concrete at elevated temperatures, as permeability is reduced so that moisture cannot escape as easily, and high stresses are generated [ 10 , 11 , 12 ].…”
