• Setting behavior of AASF cements is studied by using UPV measurements. Early-age reaction process monitored ultrasonic Specific ranges are suggested to estimate the setting time in cements. One shortcomings alkali-activated materials concrete applications quick that has been poorly understood. The objective this study explore sodium silicate-activated slag-fly ash P-wave velocity. effect inco...

In this work, we have synthesised a mixture consisting of sodium calcium silicate and nanostructures in the presence absence hydrothermal method. The product...

Abstract Mesoporous silica was prepared using sodium silicate as a precursor and Cetyl Trimethylammonium Bromide (CTAB) templating agent. The adsorption ability of enhanced by DMA (dimethylamine) modifier glycidoxypropyltrimethoxysilane (GPTMS) linking compound. process carried out incorporating the chloride solution into DMA-modified mesoporous silica, followed desorption flowing acid solution...

This is a safety assessment of silica and the related cosmetic ingredients: alumina magnesium metasilicate, aluminum calcium sodium silicate, aluminum iron silicates, hydrated silica, and sodium potassium aluminum silicate. These ingredients are synthetic amorphous silicas and silicates; crystalline silica is not a cosmetic ingredient and is not used in cosmetics. These ingredients are used as ...

H. F. Wang, J. J. Lu, K. F. Chen, H. L. Duan, Wuhan Textile University, Wuhan, China A new method to treat four solid wastes of sodium silicate used sands, dewatered municipal sludge, clay sands sludge and waste polyethylene, was discussed. About wt/ 50 % sodium silicate used sands and wt/ 50 % dewatered sludge were mixed, and then cured by microwave with a certain thickness film of clay sands ...

The flowability of spray-dried laundry detergent is important for manufacturing process performance and reliability, product quality; it strongly dependent on formulation. In this work, a detailed study four model formulations provides fundamental understanding the role particle composition, micro-structure, powder flow behaviour. All powders studied contained sodium salt linear alkylbenzene su...

We have developed a concrete material exhibiting self-healing properties and corrosion inhibition. This system involves a sodium silicate solution stored in polyurethane microcapsules present in the concrete matrix. The sodium silicate, released when the capsules are ruptured by propagating cracks, reacts with the calcium hydroxide in cement and produces a C-S-H gel that partially heals the cra...

The structure of metastable, incommensurately modulated Na(2)Si(3)O(7) has been determined from single-crystal X-ray diffraction data. In contrast to previous investigations which stated that the compound crystallizes in an orthorhombic space group, this study shows that the compound is monoclinic with a pseudo-orthorhombic cell and is affected by twinning. The structure is described in the (3 ...
