Description
При исследовании сейсмостойкости, например, гидросооружений известно применение различных материалов, в частности гипса и цемента с легкими добавками резины, целлулоида и других. Однако эти материалы не удовлетвор ют по своим физико-механическим свойствам основным требовани м моделировани (высокий модуль упругости, завышенные значени коэффициента Пуассона, сложна технологи изготовлени моделей гидросооружений и т. д.).In the study of seismic resistance, for example, hydraulic structures, the use of various materials is known, in particular gypsum and cement with light additions of rubber, celluloid, and others. However, these materials do not satisfy the basic requirements of modeling in terms of their physicomechanical properties (high modulus of elasticity, overestimated values of Poisson's ratio, complex technology of making models of hydraulic structures, etc.).
Предлагаетс материал, дающий возможность снизить модуль упругости при сохранении свойств, соответствующих свойствам бетона, используемого в известных конструкци х. Сущность изобретени заключаетс в том, что в состав цементно-песчаного раствора ввод тс совместно резинова крошка и гелеобразный бентонит.A material is proposed that makes it possible to reduce the modulus of elasticity while maintaining properties consistent with the properties of concrete used in known structures. The essence of the invention is that rubber crumb and gel-like bentonite are introduced together in the composition of the cement-sand mortar.
На один литр материала расход компонентов составл ет: п ртландцемента - 300 г, резиновой крошки - 400 г, бентонита гелеобразного- 400 г, песка - 400 г, воды - 140 г.One liter of material consumption of the components is: rtland cement - 300 g, crumb rubber - 400 g, gel-like bentonite - 400 g, sand - 400 g, water - 140 g
Резинова крошка (объемный вес 0,4-0,5 кг/дм) представл ет собой порошкообразную волокнистую массу, получаемую переработкой отходов резиновых изделий. Песок (фракци 0,5 мм) вводитс дл повышени жесткости. Бентонит (аскангель) представл ет собой глину, состо щую из минералов монтмориллонита и бейделлита и слул ;итдл повышени пластичности и удобоукладываемости смеси.Crumb rubber (bulk weight 0.4-0.5 kg / dm) is a pulverulent pulp obtained by recycling rubber waste. Sand (fraction of 0.5 mm) is introduced to increase stiffness. Bentonite (Ascangel) is a clay consisting of the minerals of montmorillonite and beidellite and slu; this increases the plasticity and workability of the mixture.
Технологи приготовлени предложенного материала не отличаетс от обычной технологии приготовлени бетона.The technology of preparation of the proposed material does not differ from the usual technology of concrete preparation.
