Abstract

The invention relates to the production of a binder and can be used in the building materials industry in the manufacture of concrete and mortars. The purpose of the invention is to increase the strength and water resistance. The method of obtaining a binder, including mixing Portland cement clinker, gypsum, mineral supplement and carbonate-containing microfiller in an amount of 20-40 wt.%, Involves preliminary heat treatment of the carbonate-containing microfiller at 180-560 ° C, which is used as a defect, a sugar production. The strength of the resulting concrete is 301 kg / cm ² , the water resistance is 6 atm. 2 tab.

Description

The invention relates to a method for producing a binder and can be used in the building materials industry in the manufacture of mortars and concretes.

The purpose of the invention is to increase the strength and water resistance.

The defecate used as a micronutrient has the following composition, May. %:

Calcium carbonate 74.2 Sugar 2.0

Nitrogen-free organic matter 9.5 Nitrogen0.9

Organic nitrogenous substances 5,9 Lime in the form of salts of various acids 2.8 Other mineral substances 3.0

Pectic substances 1, 7 When preparing a concrete or mortar mixture, the defecate selected at a sugar factory is dried to a constant weight at 180 -. The dosage of the components of the mixture and defecation is carried out by weight method. Depending on the intended use of the mixture, the amount of introduced defecation is 20-40% by weight.

DP test used in the next composition, May. %: Portland cement 60 - 68; defecate 20-50 (dried to constant weight at 180-560 C).

Concrete and mortar mixes are prepared on the basis of portland cement, defecate and aggregates. The results of the test; Tanks of these mixtures are given in Tables 1 and 2.

sd

As follows from the table. 1 and 2, the strength and impermeability of the concrete, tested in concrete and mortar, exceed those of the known

20-40% by weight of mineral clinker, gypsum, mineral supplement and carbonate-containing microfiller, characterized in that, in order to improve strength and impermeability, defecate is used as a carbonate-containing microfiller; preliminarily

in the gambler

Lormula invention

KMT mixing portland cement is processed at 180-560 C. Table 1

Claims (1)

Claim A method of producing a binder, including boiling batch, mixing Portland cement clinker, gypsum, a mineral additive and a carbonate-containing micro-filler in an amount of 20-40 wt.%, Characterized in that, in order to increase strength and waterproofness, a defecate is used as carbon-containing micro-filler - sugar waste production, which is pre-heat treated at 180 - 560 C.
