The invention relates to a panel, in particular a floor panel, suitable for forming a floor covering, wherein the panel has a substantially planar top side, and a substantially planar bottom side, at least four substantially linear side edges comprising at least one pair of opposite side edges, preferably provided with locking means.
摘要:
A structural material composition comprises: a geopolymer matrix, the geopolymer matrix formed from an alumina silicate source and an alkaline activator; and an antibacterial agent (e.g. biocide and/or heavy-metal based antibacterial agent) encapsulated in an antibacterial agent carrier to form a first plurality of encapsulated antibacterial agent particles. The first plurality of encapsulated antibacterial agent particles is integrated with the geopolymer matrix during polymerization.
摘要:
The present invention provides an apparatus and a method for producing cement through flue gas desulfurization, and specifically provides an apparatus and a method for simultaneously producing magnesium sulfate cement during a magnesium oxide based flue gas desulfurization process. The apparatus of the present invention includes a flue gas desulfurization equipment, a concentration equipment, a crystallization equipment, a centrifugation equipment, a drying equipment, a waste ash supplying equipment, a slag material supplying equipment, a mixing equipment, etc. By adopting the apparatus and method of the present invention, the problems in the present conventional cement production such as high energy cost, severe damage to the environment and so on can be solved, and the problems like high production cost of ordinary magnesium sulfate cement and high transportation cost of supplies thereby causing incapability in a large scale market spreading and application can also be solved.

Cementitious compositions and methods for producing the cementitious compositions are described herein. The methods can include mixing a compound of the general formula MaSibXcOd, MaSibXcOd(OH)e, MaSibXc(OH)e, or MaSibXc(OH)e.(H2O)f, wherein M comprises a metal that can react with carbon dioxide in a carbonation reaction to form a carbonate, Si forms an oxide during the carbonation reaction, X is an element other than M or Si, a, b, d, e, and f are greater than zero, and c is zero or greater, with a rapid setting hydraulic cement to produce a cementitious mixture. The methods can further include hydrating the cementitious mixture and carbonating the cementitious mixture. Carbonating the cementitious mixture can occur simultaneously with hydrating the cementitious mixture or subsequent to hydrating the cementitious mixture. In some embodiments, the non-hydraulic cement can comprise wollastonite. The hydraulic cement can be in an amount of from 5 wt % to 80 wt % of the cementitious composition.
