“…Firstly, the packing of the mixture is improved by the applied LP as it is finer than slag particles (see Blaine fineness), leading to a better flowability. A similar phenomenon was found by Brouwers and Radix [33] and Quercia et al [34] that an improved packing of mixtures leads to a better spread flow. Secondly, due to the presence of sodium carbonate in the solution, the dissolution of LP is prohibited because of the saturation limitation.…”

This study aims to investigate the effect of limestone powder (LP) on the reaction of sodium carbonate activated slag. The results show that the incorporated LP up to 30% improves the strength development, especially at advanced curing ages. A slightly accelerated reaction is observed for samples containing low amount of LP (B5%), while mixture with 10% LP shows the optimized results with respect to the heat release and strength development. Chemical effect of incorporating LP is observed at high replacement levels (C15%), indicated by the formation of a new phase, natron (Na 2 CO 3 Á10H 2 O). Besides, relatively high contents of hydrotalcite-like phases are generated when increasing the dosage of limestone powder. The chemical changes, including the volume changes of generating natron and the transformation of natron to calcite, is potentially responsible for the enhanced mechanical properties.

“…Applying 55% of coarse aggregate, 15% of glass powder, 40% of silica fume, and 1% of Polycarboxylate Ether to achieve optimum L-box with 0.76 ± 0.03. This result agreed with previous study [8,9] that composition of mortar plays an important role in making self compacting concrete. Compressive Strength.…”

Abstract. This paper's objectives are to learn the effect of glass powder, silica fume, Polycarboxylate Ether, and gravel to optimizing composition of each factor in making High Performance SCC. Taguchi method is proposed in this paper as best solution to minimize specimen variable which is more than 80 variations. Taguchi data analysis method is applied to provide composition, optimizing, and the effect of contributing materials for nine variable of specimens. Concrete's workability was analyzed using Slump flow test, V-funnel test, and L-box test. Compressive and porosity test were performed for the hardened state. With a dimension of 100x200 mm the cylindrical specimens were cast for compressive test with the age of 3, 7, 14, 21, 28 days. Porosity test was conducted at 28 days. It is revealed that silica fume contributes greatly to slump flow and porosity. Coarse aggregate shows the greatest contributing factor to L-box and compressive test. However, all factors show unclear result to V-funnel test.

“…Therefore, when the cement is replaced by FA, GGBS or LP, the particle packing of the whole solid skeleton is only slightly affected. In this study, the modified Andreasen and Andersen model is utilized to design all the concrete mixtures, which reads as follows [43,[86][87][88]:…”
