Alkali-activated slag (AAS) is a widely appreciated hydraulic inorganic binder and has been investigated in many studies as an alternative cementitious binder to ordinary Portland cement (OPC) in many applications [1,2,3,4].This is mainly attributed to their fresh and hardened properties comparable to OPC, and excellent durability performance against various modes of degradation …
When the acidificiation agent is added to the alkali metal silicate at a certain point during the process, the silica starts precipitating. The addition of the acidification agent is continued until the M 2 O of the alkali metal silicate (M being the alkali metal) of the ultimate silicate is less than about 1% by weight. Thus, as a general rule ...
The silica gel tube and the DNPH-impregnated cassette are suitable for monitoring the 0.05 ppm ceiling limit. The passive badge, with a 0.02 ppm limit of detection, is considered marginal at the Americal Council of Governmental Industrial Hygienists (ACGIH) ceiling level.
The suspension obtained after reaction is filtered using various solid/liquid filters. After filtration, salts are washed-out. The silicate is dried, and further processed by milling or granulation depending on the required properties of the final product. Talc (E 553b) Talc is a naturally occurring substance.

The use of silica in tires may also have an effect on the recycling of tires as tire derived fuel (TDF), which currently consumes the largest volume of scrap tires. Replacing 1.1 kg of carbon black with non-combustible silica in an average 13.6 kg passenger …
ORGANIC LABORATORY TECHNIQUES 3 3.3 c. Hot filtration Never heat organic solvents with a Bunsen burner. Use a hot plate or a hot water bath on a hot plate. Sometimes during a gravity filtration, crystals can start to grow in the filter funnel and may block the
The invention relates to a process for preparing a precipitated silica, to precipitated silicas, and to uses thereof. The process of the invention generally includes reacting a silicate with an acidifying agent, so as to obtain a suspension of precipitated silica; filtering the precipitated silica to obtain a filter cake; subjecting the filter cake to a liquefaction operation to form a second ...
The best method is to use a rotary precoat vacuum filter. In this, the rotating drum of the filter is coated with a 2-3 cm layer of precoat material, preferably perlite (an expanded or "puffed" lava, principally aluminium alkali silicate) because it gives a more porous medium than diatomaceous earth (kieselguhr) and so does not block as easily.
Due to its high activation efficiency, waterglass has been widely used for alkali activations in geopolymer. In this study, the n(SiO 2)/n(Na 2 O) (Ms) of waterglass was selected as the variable to investigate the role of the silicate structure on the mechanical properties of harden pastes. Ms was changed by the addition of NaOH to obtain the different silicate group, structure and experiments ...
The extraction of silica gel, sometimes also known as white carbon black, is based on the following, : (1) SiO 2 + 2 NaOH = Na 2 SiO 3 + H 2 O (2) Na 2 SiO 3 + H 2 SO 4 = SiO 2 + Na 2 SO 4 + H 2 O When amorphous silica contained in the RHA is dissolved in alkaline solution, a silicate solution forms that has a solubility of 876 mg/L in water ...
This invention relates to manufacture of alkali metal silicate solutions; and it comprises a process of preparing solutions of sodium silicate, for example, from the usual silicate glasses which are produced by fusion methods; said process comprising preheating water to a temperature of at least about 1000 C. and contacting such a silicate glass therewith in the substantial absence of ...
Magnesium silicate absorbent (xMgO·ySiO 2 ·nH 2 O) is an amorphous porous, white freely flowing granule or powder. As an amphoteric adsorbent, it has been extensively used in aftertreatment of polyether polyol to remove K + (Na +) ion, acid, alkali, pigments and odorous compounds containing sulfur and nitrogen atom.

Its high porosity and specific surface area ...
Filtration can be compared to a sieve or micro-strainer that traps suspended material between the grains of filter media. However, since most suspended particles can easily pass through the spaces between grains of the filter media, straining is the least important process in filtration.
