“…As the percentage of slag in the mixture increased, the compressive strength decreased for white and OPC. The results agree with the results reported by (8)(9)(10)(11). Petkova et al (12) reported that neat white cement is characterized by loss of mass below 5%, a part of which due to dehydration of both crystal water and structural water from the decomposition of C-H and C-S-H , and the other to the de-carbonization of calcite.…”

“…With increased chloride concentration, compressive strengths were decreased as shown in figure 3 (a, b, c) and figure 3 (d, e, f) depicted that compressive strength increase with age but decrease with chloride exposure for both the concrete as expected [10]. This may be because presence of higher percentage of alumina reacted with chlorides, forms friedel's salts and refines micro pores structure improves the strength [11]. In general the compressive strengths were increased for chloride exposure compared to control concrete for w/b ratio 0.45 and 0.5, which is lower for w/b ratio of 0.55.…”

Abstract. The present paper is aimed to investigate the influence of Metakaolin (MK) and Portland slag Cement (PSC) on corrosion behaviour of concrete. For this purpose, Ordinary Portland Cement (OPC) was replaced by 15% MK by weight and readymade available PSC were used. The standard concrete specimens were prepared for both compressive strength and half-cell potential measurement. For the aforesaid experiments, the specimens were cast with varying water to binder ratios (w/b) such as 0.45, 0.5 and 0.55 and exposed to 0%, 3%, 5% and 7.5% of sodium chloride (NaCl) solution. The specimens were tested at wide range of curing ages namely 7, 28, 56, 90 and 180 days. The effects of MK, w/b ratio, age, and NaCl exposure upon concrete were demonstrated in this investigation along with the comparison of results of both MK and PSC concrete were done. It was also observed that concrete with MK shows improved performance as compared to concrete with PSC.

(38) concluyeron que las mejores prestaciones mecánicas se lograban con morteros con los mismos contenidos en LC (10%) y GGBS (30%) que los estudiados aquí. En consecuencia, se determinó que el porcentaje óptimo de reemplazo de los LC era del 10%.…”
