1. Introduction . Thermal stresses in mass concrete often rise due to the hydration of cement. The temperature differences in mass concrete may vary during its placement [1,2].The temperature at the core is significantly higher than at the surface due to the entrapment of heat that adversely affects the concrete properties owing to thermal stresses and may lead to cracking [].

Ali Reza Bagheri2 incorporated silica fume in concrete with By the use of ternary mixes, 28 day durability properties of various dosages (2.5,5,7.5 and 10 %) conducted RCPT slag based blended concrete was increased compare to the ,results showed that there is reduction in charge passed at all conventional concrete with addition of

Aug 31,  · Alaa M.Rashad et.al14 investigated on ternary blended concrete consisting of fly ash and silica fume with various replacement levels (FA 60%, SF 10% and FA 50%, SF20%), binary mix of 70 % of FA level and control concrete (CC). when compared these mixture like CC vs FA60SF10 vs FA70 and FA50SF20 vs CC vs FA 70, when the 70 % replacement of fly

Abstract Controlled low strength materials (CLSM), is a self-flowing cementitious backfill material, most suitable for sustainability objectives since it makes use of wastes in large quantities. Wasted gypsum wall boards (drywalls), a construction & demolition waste, are known to pollute atmosphere by releasing harmful H2S gas when dumped at landfills.

Modified polyurethane prepolymer was prepared using the segmental synthesis method. Then, pectiniform polycarboxylate was synthesized at normal temperature in the complex initiation system of H2O2, APS, sodium bisulfite, Vc, and Rongalit according to the free radical polymerization reaction mechanism, using TPEG, AA, and PEG as raw materials and TGA as the chain transfer agent.

2.2 Mixture proportions, test specimens, and methods. The concrete mix proportions used in this study are given in Table 4. Concrete mix design was conducted using the absolute volume method. Ferronickel slag aggregate was used to replace 50% and 100% volume of sand. The water‐binder ratio was kept constant for all the mixes.

First, it can be seen that the use of paraffin is the most frequent no matter in which regions, and the maximum use frequency is up to 87.5%. It may be based on the reason that paraffin mixtures in different mass proportions have a wider phase change temperature range and higher phase change latent heat.

Rheological effects of adding two bitumen waxes (isolated from SEC−II fraction) to three bitumens were studied using dynamic mechanical analysis (DMA). Also, a commercially available slack wax was used in the study. The results show that the magnitude and type of effect on bitumen rheology depend on the bitumen and type of crystallizing fraction in the bitumen.

Concrete mixtures can be very durable even in very aggressive environments. Concrete permeability is one of the main factors that governs reinforced concrete durability when exposed to chloride or sulfate ions. This project seeks to determine the correlation between the concrete mixture proportions for ternary
