Backfill for a mine contains a main component of conventional backfill material and a flow enhancing superfine material component mixed with the main component. The superfine material component may be a clay, for example, and has a particle size of less than 1 micron. The superfine component ...
In water, clay-PS particles aggregated together, in which PS chains collapsed forming nanosized hydrophobic domains and hydrophilic clay faces stayed in ... Y Wu,Z Jian,H Zhao - 《Journal of Polymer Science Part A Polymer Chemistry》 被引量: 75发表: 2010年 Biohybrid barrier films from fluidi...
The objective of this research is to study the effects of feed concentration and temperature on the pervaporation of ethanol-water mixtures using polyvinyl alcohol (PVA) zeoliteclay membranes. The liquid feeds for the pervaporation were prepared using different weight concentrations of ethanol which were...
A comparison is done for a model material (mixture of sand and clay) with and without water repellent substances, being the samples with water repellent substances in a subcritical water repellent state (contact angles <90掳). Wettability was manipulated by treatment with organic acids that mimic...
The assembly has flexible cotton cover containing a mixture of polymer and clay, where the cover is dipped in cold water at oscillating temperature between 5 degree and 15 degree. The water is absorbed by the polymer clay mixture for redistributing freshness via stored water. Contents of the co...
Building with cob: building with cob--a simple mixture of clay subsoil, aggregate, straw and water--brings us full circle from today's soulless, square houses erected from mass-produced materials to techniques from the past that really worked and that honor the land on which we are building...
adequate flowability (by inclusion of water-reducing admixture (WRA)), short setting time (by using accelerator such as sodium metasilicate (SS)), and acceptable printing quality in terms of surface quality, dimension conformity (by utilizing nanoclay (NC)), and buildability (by addition of SF...
is acid, both in water and in KCl. The difference between pH values for these two conditions is negative and close to zero, indicating a small predominance of silica clays. The value obtained for the exchangeable aluminum (Al) is larger than 0.60mE/100ml and is considered high. In ...
Cement comprises 10 to 20 percent of concrete and is made of limestone combined with silica sand, aluminum, clay, or another type of fine aggregate that reacts with the limestone or calcium to form a sort of paste – called a binder. ...
2. Material and methods 2.1. Material The material studied is a compacted mixture of Wyoming MX-80 bentonite (commercial name Gelclay WH2) and quartz sand (commercial name TH1000) with a proportion (in weight) of sand of 30%. The mixture was provided in boxes. Actually, examination of th...
