V. Прочитайте и письменно переве­дите на русский язык с 1-го по 3-й абзацы текстаCementing materials

1. Lime, gypsum and cement are the three materials most widely used in building construction for the purpose of binding together masonry units, such as stone, brick and as constituents of wall plaster. Cement is furthermore the most important component of concrete. These materials form very important elements in all masonry structures. As a class they are designed as cementing materials.

2. The gradual improvement in Portland cement quality from the time of its introduction led to the elaboration of rapid hardening Portland cement, or "high early strength". Later developments include low heat and sulphate resisting cements, also white and coloured cements. Another important class of cement is high alumina cement. High alumina cement is a material containing alumina. It has an extremely high rate of strength increase which is, owing to the violence of the chemical reaction, accompanied by a considerable evolution of heat. It is very resistant to chemical attack.

3. It therefore follows that Portland Cement like other materials can to some extent be modified to suit a particular application. The scope for such purpose-made cements has led to the development of an increasing variety such as high alumina cement, blast­furnace slag and pozzolanas. Portland blast-furnace cement has greater resistance to some forms of chemicals.
