Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, stable at elevated temperatures, making a suitable additive for refractory non-shaped materials and various shaped products. In this study, employed as 50 % clay replacement ceramics up 30 cement mortars. Physico-mechanical pr...

The objective of this work was to produce brushite cement for orthopedic applications, based on the system wollastonite/phosphoric acid with incorporation polyethylene glycol (PEG) as a setting and processing additive. Brushite/PEG obtained by dissolution-precipitation method its physicochemical properties were characterized X-ray diffraction, compressive strength, porosimetry, biological behav...

Portland Cement Concrete (PCC) pavement was studied with incorporation of an environmentally friendly eco-additive, sodium acetate (C2H3NaO2). This additive added to PCC in three different percentages 2%, 4% and 6% binder weight. For a comprehensive elucidation the eco-additive on performance pavement, casted samples were cured environments, namely: water, outdoors pond water. Water absorption ...

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 ...

The article presents the results of optimization cement composition according to criteria compressive strength and bending by methods mathematical planning experiment. As a result studies, compositions increased were obtained using activated closure water, as well tandem water (AB) + plasticizer AB adhesive additive. At optimal content components, gain up 18% is achieved.

A thermoset PMS (Polyvinyl modified silicone) type polymer additive effect on load bearing capacities of cement grouted rock bolt specimens exposed to thermal cycles was investigated with a series experimental studies. The used in this study liquid phase while adding into the fresh mix and started solidify by polymerization after being mixed well grout. silicone based product selected use becau...
