The article is devoted to the study of effect lime kiln dust (LKD) on properties concrete mixtures and using Portland cement fly ash. A possible mechanism for formation structure cement–ash paste with addition LKD analyzed in detail. positive hydration (an increase content water by 40.50%) due an alkalinity shown. Using method experiment mathematical planning, experimental–statistical polynomia...

Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

This study aimed to evaluate the influence of adding plastic bottle fibers soil-cement mixtures and possible improvements generated by addition a blend two types additives, namely, additive 1 (waterproofing improver) 2 (adhesion enhancer), in compactability shear strength parameters soil-cement-plastic fiber mixtures, considering tropical residual soil. The used this are made Polyethylene Terep...

The paper presents the results of studies to determine suitability dump battle fired ceramic products based on kaolin clays Angren deposit, positive effect addition fractionated formation structure and physico-mechanical properties portland cement stone is established. For use as an additive in cement, need for fractionation production waste with separation burnt part was noted; its chemical mi...

The study is devoted to the modification of 42.5 class ordinary Portland cement with a 10% special expanding additive (cement powder and gypsum in 40:60 percentage ratio), impact this on mortar determined. Using modified multi-fraction quartz sand ratio 1:3, prism-shaped samples size 4x4x16 cm were fabricated, left water bath for 24±2 hours after formation. After one day curing, demolded, their...
