    Abstract: An alkali resistant glass composition having improved durability to withstand highly alkali environments at elevated temperatures, such as curing of cementitious products in an autoclave, is conveniently formed from economical and abundant materials. The glass composition includes increased levels of calcium and iron, and relatively low levels of alkali metals, as compared to many other alkali resistant glass products, and comprises essentially of, by weight, >35% Si2O3, 1-25% CaO, 1-15% Fe2O3, 1-10% R2O, and an amount of Al2O3 such that the ratio of Si2O3:Al2O3 is greater than or equal to 1. Alkali resistance can be improved by forming a passivity layer on the surface of glass articles by treating the articles hydrothermally in a basic environment. Optionally zirconia and/or titania may be added to the composition to further improve alkali resistance.

    Abstract: The present invention relates to a method of manufacturing composite particles that work as a binding agent, the composite particles containing a limestone portion, which is based on limestone particles or limestone silicate rock particles and which is mixed with a kaolin portion that comprises kaolin particles. In the method, the limestone portion or the kaolin portion is subjected to calcination before they are mixed with each other, or the mixture of these portions is subjected to calcination, whereby, the activated layer on the surfaces of the particles of, at least, one of the said portions that was formed in the calcination makes the particles of the portions to attach to each other into composite particles. The invention also relates to the composite particles thus produced, the concrete that is formed by these, and equipment that is suitable for the implementation of the said method.
