Abstract
FIELD: preparation of concrete mixes with complex additions in production of monolithic and prefabricated reinforced concrete. SUBSTANCE: method involves mixing the equal parts of gas-purification dust with part of mixing water, then with alkali-treated lignosulfonates, dusted wood resin, holding the produced addition followed by mixing it with the remaining part of mixing water and sand, then with cement and crushed rock. Mobility of concrete mix is up to 20 cm. EFFECT: higher mobility of concrete mix. 1 tbl
Description
Изобретение относится к способам приготовления бетонных смесей, содержащих комплексные добавки и используемых при производстве монолитного и сборного железобетона. The invention relates to methods for preparing concrete mixtures containing complex additives and used in the production of monolithic and precast concrete.
Цель изобретения повышение подвижности бетонной смеси. The purpose of the invention is to increase the mobility of the concrete mixture.
Для проведения сравнительных испытаний готовят смесь контрольного состава (без добавок) на 1 м3 бетона содержит: цемент 380 кг; песок 600 кг; щебень 1200 кг; вода 190 л, при осадке конуса 5-8 см.For comparative tests, a control mixture is prepared (without additives) per 1 m 3 of concrete; it contains:
Для приготовления образцов кубиков 100 х 100 х 100 применяют следующие материалы: вяжущее портландцемент марки 400 активностью 41,5 МПа, песок с модулем крупности 1,3; щебень гранитный фр. 5-20 мм; лигносульфонаты, обработанные щелочью (ХДСК 1, ВСН 65.0.9-82), смолу древесную омыленную при ρ 1,012 г/см (ТУ 81-0-02-78), минеральную добавку пыль газоочистки производства ферросилиция (ПГПФ) (см. таблицу). For the preparation of 100 x 100 x 100 cubes samples, the following materials are used: cementitious Portland cement grade 400 with an activity of 41.5 MPa, sand with a fineness modulus of 1.3; granite crushed stone fr. 5-20 mm; lignosulfonates treated with alkali (HDSK 1, BCH 65.0.9-82), saponified wood resin at ρ 1.012 g / cm (TU 81-0-02-78), mineral additive gas cleaning dust produced by ferrosilicon (PHPF) (see table) .
Предварительное перемешивание ПГПФ с водой и пластифицирующей добавкой смолы древесной омыленной позволяет изменить соотношение ПГПФ и воды до (1: 1) и хранить комплексную добавку в течение 0,1-120 сут, без изменения ее реологических свойств и расслоения. Pre-mixing PHPF with water and a plasticizing additive of saponified wood resin allows you to change the ratio of PHPF and water to (1: 1) and store the complex additive for 0.1-120 days, without changing its rheological properties and separation.
