This paper demonstrates the transformation of industrial residue (copper slag) a Swedish mining and smelting company “Boliden”, through geopolymerization, into advanced building materials. The main objective this experimental study is assessment appropriate conditions for preparation alkali-activated slag-based geopolymer pastes with further foaming production, by aluminum powder addition. alka...

Mechanical activation is known to greatly influence the reactivity of fly ashes. In this paper, we report a comparative study properties alkali-activated geopolymer materials prepared using both ball-milled and attrition-milled Ball milling was carried out for 30 min 60 while attrition continuously in high-speed attritor. The surface area raw ash decreased from 4017 cm2/g 3999 3912 after ball m...

Three kinds of taro paste were prepared with taro:water:sugar ratios of 1:0.33:1.4, 1:0.33:0.8 and 1:0.33:0.2. Results indicated that the paste with the highest sucrose concentration had the least hard texture. The retarding effect of sugar on hardness development and water mobility of the low concentration system was fructose > glucose > lactose > sucrose. The DSC characteristics showed that a...

This study aimed to evaluate by the intra-osseous implant technique the most commonly used materials for pulp therapy in pediatric dentistry: calcium hydroxide (CH), Guedes Pinto paste and CTZ paste, according to FDI (1980) and ANSI/ADA (1982) recommendations. Thirty guinea pigs, 10 for each material, divided into experimental periods of 4 and 12 weeks received one implant on each side of the l...

Waste palm oil products can be recycled in the production of pervious geopolymer concrete (PGC) for long-term sustainable development. PGC is a non-slip porous pavement that allows water to pass through. Biomass aggregate (BA) produced by burning biomass and introduced as replacement natural (NA). BA mixed with fly ash (FA) alkaline liquid (AL) heated an oven at 80 °C 24 h produce coated (CBA)....

The objective of this study was to investigate the effect curing temperature on mechanical properties sanitary ware porcelain powder-based geopolymer paste and mortar under various temperatures. setting time, porosity, water absorption, compressive strength specimens mixed with alkaline concentrations 8M, 10M, 12M, 14M were compared. All cube (50×50×50 mm) placed into drying ovens for 24 hours ...

BACKGROUND Copy and paste functionality can support efficiency during clinical documentation, but may promote inaccurate documentation with risks for patient safety. The Partnership for Health IT Patient Safety was formed to gather data, conduct analysis, educate, and disseminate safe practices for safer care using health information technology (IT). OBJECTIVE To characterize copy and paste e...

Abstract The study was conducted to investigate the feasibility of sodium aluminate activation nonferrous waste foundry sand. aim solidify sand via geopolymerisation into useful civil engineering materials. Green mixed with make a paste which filled 50 × mm 3 mold. mixture cured in an oven for 5 days. concentration aluminate, granulated blast furnace slag (GBFS) : (WFS) ratio, liquid solid rati...
