For ordinary Portland cement, the main raw materials are:
1.Calcareous raw materials (mainly providing calcium oxide), mainly limestone, marl, shells, etc.;
2.Clay raw materials (mainly providing silica, alumina and some iron oxide): mainly loess, clay, shale, mudstone siltstone, etc.
3.Correction raw materials: In order to make the composition of cement raw meal meet the requirements of ingredients, corresponding correction raw materials can be added if necessary, such as iron correction raw materials (low-grade iron ore, pyrite slag), siliceous correction raw materials (sandstone, siltstone, etc.), aluminum correction raw materials (fly ash, cinder, gangue, etc.).
If you want to know more about these raw materials, I recommend that you take a look at the book on petrography of inorganic materials.
There are also a variety of special-purpose cements, which are made from different raw materials, but Portland cement is the most commonly used.
The production of cement is generally "two grinding and one burning", that is, the raw materials are first crushed, ground into powdery cement raw material through grinding, and then calcined to form clinker, and the clinker is crushed and ground again to make finished products.
Ordinary building bricks belong to clay bricks, the main raw material is clay, the clay is mixed with other auxiliary raw materials and grinded, and then processed and formed on the brick press, generally made into a cuboid, and sent to the kiln for calcination after molding.
I studied inorganic non-metallic materials engineering, and I hope it can be helpful to you.

Limestone and clay are the main raw materials, and different cements will add other things to increase the strength and setting time, but this is the main thing
Burnt bricks are just ordinary clay.
-
Cement: limestone + clay;
Brick : clay.
-
The cement is limestone.
Ordinary burnt bricks are clay.

There are many kinds of raw materials available, including wet ash discharge, dry ash discharge, mixed ash discharge, slag, spontaneous combustion coal gangue, stone powder, stone nitrate (small stones), sand, ceramsite, tailings sand, volcanic ash (slag), steel slag, calcium carbide slag, water quenching slag, air quenching slag, heavy ore slag, smelting slag, water slag, dry slag, sulfuric acid slag, phosphate fertilizer slag, alkali slag, aluminum plant red mud, calcium carbide mud, electrolytic copper slag, industrial waste slag, waste ceramic slag, waste brick powder, shale, construction waste, etc.
The cost of bricks depends on many factors, your equipment, your recipe and so on.

The raw material of cement is mainly silicate, but there are also other types of salt-based cement, bricks are made of clay, which is a very mixed material. There is a kind of hollow brick that should meet your requirements, as if it is made of carbon slag or construction waste with light weight and high strength, as for frost resistance, I don't know
-
Cement brick, also known as ordinary concrete small hollow block, is made of cement as cement, ordinary sand or heavy slag as coarse and fine aggregate, and is stirred, formed and cured by adding water.
-
Fly ash is also one of the raw materials for making cement bricks, if the proportion of fly ash for hollow bricks can not exceed 30% (depending on the actual raw materials), the products of cement bricks are good or not, and the raw materials and production equipment are related.
-
Now the common cement brick materials on the market mainly include stone powder and brick slag, stone powder is the most common, and brick slag is a new type of raw material advocated by the policy.
Welcome to consult and adopt.
-
Cement brick is a new type of wall material made of fly ash, cinder, coal gangue, tailings slag, chemical slag or natural sand, mud mud, etc. (one or more of the above raw materials) as the main raw materials, using cement as a coagulant, and calcining at high temperature.

The earliest cement was made by the English engineer JSmitton discovered in 1756 while studying the properties of certain limes for hardening in water that to obtain hydraulic lime, limestone containing clay must be used for firing.
Burning bricks is early, China in the Spring and Autumn Period and the Warring States Period successively created square and elongated bricks, Qin and Han Dynasty brick-making technology and production scale, quality and fancy varieties have significant development, known as "Qin bricks and Han tiles". Artificial small blocks used in construction, divided into sintered bricks (mainly referring to clay bricks) and non-sintered bricks (lime sand bricks, fly ash bricks, etc.), commonly known as bricks. Clay bricks are made of clay (including shale, gangue and other powders) as the main raw material, which is processed by mud treatment, molding, drying and roasting.
Please feel free to use it, there should be no problem, we have cement bricks for multi-storey houses below seven floors. >>>More
Cement brick machine is a new model designed according to China's national conditions, combined with the opinions of new and old customers, with high production quality, strong durability and high production efficiency, and is suitable for the production of various strength environmental protection bricks, interlocking blocks, parking lot grass bricks, hollow blocks, etc. The products produced have high compressive strength, standard specifications and sizes, and beautiful appearance. It realizes automatic operation, adopts hydraulic transmission, double-layer fabric (base material and colored fabric), and has the function of vibration pressurization, height and compactness. >>>More
The choice of automatic cement brick machine needs to consider the output, raw materials, use, total power, transmission mode, vibration frequency, and other factors, such as the type of brick machinery, concrete machinery, cement machinery, etc.; Uses include building materials factories, brick making, construction sites, etc.; The total power is 50kw, 100kw, 8kw, etc. The ** of automatic cement brick machine is about 100,000 yuan to hundreds of thousands of yuan per unit. Before you choose, it is recommended that you have a full understanding and comparison of the automatic cement brick machine, and you can consult Jiangsu Tengyu Machinery Manufacturing Co., Ltd.
The equipment of Yinma Intelligent Brick Machine Company can be divided into large, medium and small in terms of scale; In terms of the degree of automation, it can be divided into four types: economical, automated, semi-automatic and fully automatic; In terms of output, there are four types of machines, six types of machines, nine types of machines, twelve types of machines and fifteen types of machines, ranging from one to the next. According to the quality of raw materials, the ease of obtaining to measure, reduce costs....Users should make all preparations before investing in a cement brick machine plant, such as the selection of the plant, the application of raw materials, the storage of raw materials, the sales volume, the storage of finished products, etc., these factors should be considered. Production site, small brick factory generally has a few acres of land should be enough. >>>More
