Abstract

FIELD: construction industry. SUBSTANCE: clay ground is moistened until full water saturation is reached and then preliminarily stirred. To a specified volume of the latter, specified volumes of sand and rubble are added followed by stirring the mixture until a homogeneous mass is obtained. To this, specified volumes of a binder and additives are added and, after mixing, a molding mixture is obtained. This mixture is a material to press articles. EFFECT: mixture for fabricating small-piece articles, wall blocks, bricks, etc obtained.

Description

 The invention relates to the field of the construction industry and will find primary application in the manufacture of small items: wall blocks, bricks, tiles, etc.

 A known method of manufacturing building products from concrete, including the dosage of clay soil, sand, binder and additives in dry form, mixing them with moisture, molding products, including by pressing, drying products (1).

 The disadvantage of the described method is the need to use equipment for mixing components, characterized by high energy consumption and low reliability due to increased wear of the working body.

 The aim of the invention is to reduce energy consumption and increase reliability.

 This goal is achieved by the fact that in the method of manufacturing products from soil concrete, including dosing and mixing clay soils with sand, gravel, binder and additives, wetting the mixture to molding moisture, pressing the product with subsequent drying, pre-clay soil is soaked until completely saturated, and during the preparation of the soil-concrete mixture, clay soil is first mixed, then sand and gravel are introduced into the clay soil, mixed until a homogeneous mixture is obtained and then a binder and additives are introduced and finally mixed and moistened to a molding moisture.

 A method of manufacturing products from concrete is as follows.

 Soak a large amount of clay soil to complete saturation, usually within 3-5 days. Depending on the size of the working volume of the mixing device and the composition of the moldable mixture, a certain amount of soaked clay soil is dosed and pre-mixed. Then, dosed volumes of sand and gravel are poured into the working device. After a certain period of time, an astringent (cement, lime, etc.) and additives are added and additional moisture is produced. Mixing is carried out to obtain a molding mixture with a given degree of uniformity.

 The duration of the listed periods of mixing is usually within 2.5 minutes, and depends mainly on the quality of the clay soil. and sand, as well as a given composition of the moldable mixture. The degree of additional moisture depends on the water saturation of the clay soil, the initial moisture content of crushed stone and sand, as well as the required molding moisture content of the soil-concrete mixture.

 Pressing and drying the product is carried out by known methods.

 Due to the exclusion of the operation of grinding the soil, energy costs are reduced and the reliability of the technological process of manufacturing building products from soil concrete is increased.

Claims (1)

 A method of manufacturing building products from soil concrete, including preparing a soil-concrete mixture by dispensing and mixing clay soil, sand, gravel, binder and additives, wetting the mixture to a molding moisture, pressing the product with subsequent drying, characterized in that the clay soil is pre-soaked until water is saturated , and in the process of preparing the soil-concrete mixture, clay soil is first mixed, then sand and crushed stone are introduced into the clay soil, mixed until a homogeneous mixture, after which a binder and additives are introduced and finally mixed and moistened to a molding moisture.
