Description
Известны легкобетопные смеси дл изготовлени строительных конструкций, включающие портландцемент, керамзитовый гравий и воду. Такие бетоны при объемном весе до 2000 кг1жл имеют обычно максимальную прочность на сжатие 300 кг/см при расходе цемента до 550 кг на 1 . бетона.Light concrete mixtures for the manufacture of building structures are known, including Portland cement, expanded clay gravel and water. Such concretes with a volumetric weight of up to 2000 kg1 of them usually have a maximum compressive strength of 300 kg / cm with a cement consumption of up to 550 kg per 1. concrete.
Предлагаемое изобретение позвол ет уменьппть обьемныр вес и увеличить прочность бетона .The present invention allows for a decrease in volume weight and an increase in concrete strength.
Это достигаетс тем, что легкобетонна смесь содержит компоненты в следующем соотношении , вес. о/оГThis is achieved by the fact that the light concrete mixture contains components in the following ratio, wt. o / oG

Объемный насыпной вес известн кового песка составл ет 1500 .The bulk bulk density of limestone sand is 1500.
Бетон из описываемой смеси имеет прочность на сжатие 300 кг/см, объемный вес 1600 кг/л при расходе цемента 400 кг на 1 /гз бетона.Concrete from the mixture described has a compressive strength of 300 kg / cm, a bulk weight of 1600 kg / l with a cement consumption of 400 kg per 1 / gz of concrete.
