Chapter I outlines the
cement is a kind of plastic water into a slurry, after mixing, can be cemented sand, stone and other appropriate material and can in the air and water hardening of the cement powder material.
cement classification
(1) Cement according to their purpose and performance is divided into three categories: general purpose Portland cement, special cement, properties of cement.
1. Universal Cement:
general industrial and civil buildings of cement is widely used in civil engineering of cement, which includes six species: Portland cement, ordinary portland cement, slag cement, portland pozzolana cement, Portland cement and fly ash composite portland cement.
2. Special Cement:
special cement is used in the name of the project named the cement, such as oil well cement, road portland cement, masonry cement.
3. Characteristics of cement:
characteristics of cement is the cement has some outstanding features, such as: rapid hardening Portland cement, low heat Portland slag cement, portland cement expansion of sulfur aluminum.
(b) the name of their main water rigid material and is divided into:
1. Portland cement, that is known outside of Portland cement.
2. Aluminate cement
3. Sulphoaluminate cement
4. Iron aluminate cement
5. Fluoro-aluminate cement
6. With volcanic ash or potentially water-rigid materials, as well as other active materials as the main component of cement

回答:
水泥基本知识
（这里有详细介绍：http://www.dcement.com/bbs/dispbbs.asp?BoardID=17&ID=231）
第一章 概述
水泥是一种加水拌合后成塑性浆体，能胶结砂、石等适当材料并能在空气和水中硬化的粉状水硬性胶凝材料。
水泥的分类
（一）水泥按其用途及性能分为三类：通用水泥、专用水泥、特性水泥。
1．通用水泥：
通用水泥是工业与民用建筑土木工程中应用较为广泛的水泥，它包括六大品种：硅酸盐水泥、普通硅酸盐水泥、矿渣硅酸盐水泥、火山灰质硅酸盐水泥、粉煤灰硅酸盐水泥和复合硅酸盐水泥。
2．专用水泥：
专用水泥是以所用工程的名称来命名的水泥，如油井水泥、道路硅酸盐水泥、砌筑水泥等。
3．特性水泥：
特性水泥是指具有某种突出特性的水泥，例如：快硬硅酸盐水泥、低热矿渣硅酸盐水泥、膨胀硫铝硅酸盐水泥等。
（二）按其主要水硬性物质名称分为：
1． 硅酸盐水泥，即国外通称的波特兰水泥。
2． 铝酸盐水泥
3． 硫铝酸盐水泥
4． 铁铝酸盐水泥
5． 氟铝酸盐水泥
6． 以火山灰性或潜在水硬性材料以及其他活性材料为主要组分的水泥
