Abstract:

Grouting cement is a type of Portland cement designed to insulate pipes of oil and gas wells and protect them from groundwater pressure, shifts of ground layers, and the negative effects of aggressive media. When solidified, the cement mortar forms a monolithic jacket, impermeable to liquids and gases. The material adheres firmly to the metal pipe and to the walls of the trunk drilled in the rock. The use of grouting cement creates conditions for safe operation of wells and prolongs their working period. In traditional construction, this type of Portland cement is not used. The exception is th

Abstract:

The vision of a sustainable world economy is currently aimed at achieving carbon neutrality and linked to global warming. According to statistics, simply burning one ton of Portland cement clinker causes at least a half a ton of carbon dioxide to be emitted. Therefore, one of the options to solve the problems identified is to revise existing technologies and develop low-carbon, low-carbon binders using industrial waste and unconditioned raw materials.

Abstract:

High energy requirements and the resulting economic demands due to the production of Portland cement leads to tendency to replace a portion of cement with secondary raw materials or to use other alternative binders. Among the commonly used cements replacements is currently fly ash which is produced during the coal combustion. In this paper the influence of cement/ash ratio in a paste on paste’s porosity is investigated using mercury intrusion porosimetry.

Abstract:

Many byproducts and waste materials with pozzolanic properties can substitute natural raw materials in cement production. Some of these waste materials like fly ash and blast furnace slag are commonly harnessed by cement industry. Others are of seldom use due to limitations of the very centralized cement production systems currently in use. In the authors opinion, it is necessary to change this system to enable efficient utilization of various waste materials that are available locally (e.g., white and red ceramics). In this study, a new partially centralized system of cement production is pro

In making cement, of course, it has to go through processes that the factory. One of the processes in making cement is grinding and drying raw materials, namely the Raw Mill. Raw Mill is the initial stage in making Raw Mix where in the Raw Mill milling, drying, mixing, and separating materials such as limestone, silica, clay, and iron sand occur. Raw Mix is the main ingredient in making clinker which is the main raw material in making cement. The quality of the Raw Mix is very influential in making cement.

Using self-leveling cement mortar, we can make a solid flat surface economically in accordance with the requirements, which is widely recognized and applied. Because of the demands of self-leveling, the mortar required materials have good liquidity and flow retention. Therefore, the raw materials must have a supporting role. Analyzing the raw materials, the paper study the effects of raw materials for the self-leveling cement mortar.

Abstract:

A method of producing portland cement using the wastes of enrichment of polymetallic ores of "Achpolymetal" (Kentau, Kazakhstan) in the amount of 0.5 to 2.5% as a mineralizing additive in the raw mixture is proposed. This allows the clinker to be produced at a lower temperature (1300–1350 °C), resulting in lower fuel consumption and higher furnace productivity. The experimental clinker is better subjected to grinding, the electric power consumption for grinding cement decreases, the grinding bodies of cement mills decrease. In the waste, there are catalytic and modifying elements. Studies have

Geopolymer cement is an aluminosilicate material which activated by the alkaline solution. With appropriate heat curing regimes, geopolymer cement could achieve an excellent performance as construction material. Apart from that, geopolymer cement is one of the alternative cementitious materials for green construction as its raw starting materials could be any pozzolanic industrial by-products. Global carbon-dioxide emission from Portland cement consumption could be reduced with the replacement of that geopolymer cement. Therefore, the development of geopolymer cement is receiving much more att

However, the specific effects of the fineness of individual raw materials on clinker burnability remain insufficiently understood. In this study, the fineness of limestone, shale, and iron-bearing materials was systematically varied to explore its influence on raw meal burnability and the resulting cement properties. Raw materials were prepared with controlled residue levels (5–20%) retained on an 80 μm sieve. Their impact was evaluated based on free lime content (f-CaO), clinker phase
