81 Production of segment made of slightly calcium leaching concrete JP11070498 1998-04-21 JPH11302054A 1999-11-02 OWAKI EIJI; MATSUOKA YASUNORI
PROBLEM TO BE SOLVED: To reduce the amts. of calcium hydroxide and low crystalline calcium silicate hydrate formed in hydrate of concrete by adjusting the calcium and silicon contents of a binder and carrying out autoclave treatment. SOLUTION: The calcium and silicon contents of a binder used in concrete are adjusted. The ratio between calcium and silicon consumed in hydration reaction in a concrete hardening step is adjusted so that one or more minerals are formed without forming calcium hydroxide and low crystalline calcium silicate hydrate when concrete causes hydration reaction by autoclave treatment. Concrete contg. the resultant binder is kneaded and subjected to autoclave treatment to accelerate hydration reaction. The leaching of calcium ions from the produced concrete member can be prevented.

In order to produce a building material covering, plates which are covered with a conductive laying material are mounted onto a mechanically stable backing material. A contact is made between the conductive laying material and a conductive junction. The resulting joints are filled with a pasty or liquid pointing substance in a substantially planar manner and said joints subsequently harden independently. The pointing substance consists of an alkali-silicate binding-agent component and a powder component which are mixed in the presence of water. The building material covering thus has good electrical conductivity, high mechanical resistance (cracking resistance) and good refractory qualities, without the addition of electrically conductive particles. The powder component preferably has an activated silicon dioxide component and an active aluminium oxy component and is devoid of calcium oxide and iron compounds.

99 ACID AND HIGH TEMPERATURE RESISTANT CEMENT COMPOSITES PCT/CZ2011000109 2011-11-14 WO2012069024A2 2012-05-31 RAZL IVAN
Process for production of acid and high temperature resistant cement composites, where the matrix is alkali activated F fly ash alone, F Fly ash combined with ground slag or ground slag alone. F - fly ash produces lower quality alkali activated cement systems. On the other hand the lack of calcium oxide results in very high resistance to medium and highly concentrated inorganic or organic acids. The high strength and low permeability of pure F-fly ash cement systems is achieved by using in the composition un-densified silica fume, the amorphous silicone dioxide obtained as by products in production of ferro-silicones. Precipitated nano-particle silica made from soluble silicates and nano-particle silica fume produced by burning silicon tetra chloride in the hydrogen stream.
