Under the condition of modern construction, specialists regularly use a composite cement-sand mixture. Also, other inert building materials such as granite rubble, expanded clay, and gravel are often added instead of sand.
Proper preparation and production features
To obtain the highest quality composition in terms of characteristics and operational capabilities, all components should be mixed in accordance with their proportions. Especially the result is affected by what percentage of water contains the finished volume of cement mortar. Precision in the manufacture of any mortar is extremely necessary to maintain its high-level operational properties-strength indicators and the ability to withstand the impact of external factors. The main technological qualities that ordinary cement has can be improved. The manufacturer for certain product brands can provide:
- water and frost resistance;
- make the consistency more fluid, which allows this homogeneous, evenly distributed mass to be poured into the formwork or applied in layers when processing various surfaces.;
- ensure the plasticity and quality of the adhesive to cover with tile materials (possibly through the use of resin additives).
The universal difference between cement is that it can serve as a base from which the necessary building material is obtained, both similar to the original one and in a different form. In particular, builders often prepare the necessary volumes of concrete mixture from it, and the plant produces reinforced concrete, achieving high mechanical strength due to the reinforcement of a rapidly hardening substance. Attention! The difference between concrete is that it is produced on a cement basis, also filling in sand and various structural elements that form the qualities of this product.
Alternative type of cement
Along with the described product, you can choose an alternative version of the binding building material. Since 1824 (date of invention), it has been called by the name of the island of Portland (England), where limestone is extracted, with which this powder has similar visual qualities. During the production process, to get this product, clinker is crushed, and then by adding chalk to it, the hydration process is regulated (thermal activity is reduced). If you perform a detailed analysis of the elements to understand the difference between Portland cement and cement, you can find the following elements in its structure::
- L Alite (tricalcium silicate);
- celite (tricalcium aluminate);
- braunmilerite (hydrochloric ferrite);
- bilite (silicate dicalcium).
Release schedule for this product:
- Preparation of raw material base.
- Production of clinker derivatives.
- Transformation of elements into cement-differs in structure and qualities.
The following mineral components are selected as raw materials for the production process:
- calcium oxide (44%);
- silicon oxide (14.5%);
- aluminum oxide (3.5%);
- iron oxide (2%);
- magnesium oxide (1.6%).
All this is extracted by mining or open-pit mining from factory complexes. The composite base should be filled with clay, limestone, iron ore components, bauxite or castings. Further technological stages, in particular, the increased processing temperature (1480 degrees Celsius), lead to the appearance of clinker building materials, which are crushed after the addition of gypsum and calcium sulfate is made. This type of building material, when mixed with water, hardens within a few hours, turning into silica gel. If you combine it with limestone (a natural plasticizer) and lime, you can create a quick installation concrete, and separate use of lime will lead to the release of another product that has sufficient fluidity for facade finishing of buildings and structures.
Difference between cement and Portland cement powder
It is not entirely appropriate to talk about the difference between cement and Portland cement, since the latter is only a type of building material, and the former is a full — fledged category of powder products. Distinguish cement (Portland cement) differences of the following nature:
- ultimate strength parameter-mechanical resistance, density and wear resistance;
- easily tolerates low temperatures;
- according to GOST, it is represented by such brands: M400, M500, M550, M600, M700, for each of which the target application is defined;
- the structure of the product is fast-hardening and moisture-resistant, since it consists of fine-grained elements;
- a minimum of rules and a simple scheme for bringing it into operational condition;
- affordable prices with an acceptable cost of raw materials.
Thus, the article indicates only a wide range of Portland cement capabilities, but this is far from the only derivative product. Depending on the fillers that are additionally included in the product structure, and their quantity, you can trace how cement differs from Portland cement, considering its completely different varieties.
Types of cement derivatives for construction work
So, by itself, Portland cement is a product used for the production of monolithic or prefabricated structures with and without reinforcement (SB). It is also possible to distinguish such varieties as slag portland cement and pozzolanic. In both cases, the products are used in different ways – on the ground, underground, and even in hydraulic structures (surface and underwater). In this category of building materials, other types of products (of a different structural format)are widely used:
- alumina and high alumina — heat-resistant, ideal for emergency engineering procedures;
- gipsoglinozemistye-bezrashadochny and expand with absolute water resistance;
- white and colored ones are in demand in architecture, sculpture, landscape design, and other creative fields.
After studying this article, the question of purchasing the appropriate types of products for small construction in private or full-fledged capital processes that are carried out on a large scale remains open
