Abstract
Modern materials science is characterized not only by the creation of high-strength building materials, but also by using a large number of raw materials and additives that improve the properties of concrete mixtures and concrete. The article considers the possibility of using both old and new generations of complex organomineral additives in concrete production. The nature of the effect of additives on the rheological behavior of cement systems and hydrate formation processes, as well as an assessment of the effect of mineral and organic additives on the composition of hydration products of cement systems, are revealed. Studies have shown that complex additives, which include hyper- and superplasticizers, lead to some slowdown in hydration and crystallization processes. The high efficiency of plasticizing additives helps to reduce water content, which in turn provides increased strength of cement concrete.
Highlights
1 Introduction The most important problem of modern industrial production is the accumulation of a huge amount of large-scale waste, a significant part of which are mineral resources. Most of these wastes with minor processing can be effectively used in the construction industry, in particular, in the production of concrete
No more than 20% of waste is used as secondary raw materials, including about 10% in the construction industry
A sharp increase in the strength of concrete with SP and HP is achieved due to a significant decrease in the water content of the mixtures, as a result of which the slowing down effect becomes not so noticeable
Summary
The most important problem of modern industrial production is the accumulation of a huge amount of large-scale waste, a significant part of which are mineral resources. Most of these wastes with minor processing can be effectively used in the construction industry, in particular, in the production of concrete. The amount of waste used in mining and processing plants is small. No more than 20% of waste is used as secondary raw materials, including about 10% in the construction industry
