Description

The paper presents the results of research on the technology of obtaining non-autoclaved structural and heatinsulating foam concretes intended for the production of soundproof panels on their basis, used in the construction of interior partitions.
A composition of non-autoclaved foam concrete of density grade D900 with compressive strength class B3.5 has been developed. The composition of the material includes: Portland cement grade M500, coarsely ground river sand, protein foaming agent and functional additives.
A technology for manufacturing panels is proposed, including separate preparation of mortar mixture and foam, their combination, mass molding and heat treatment in cassette units.

Abstract (Russian)

В работе представлены результаты исследований по технологии получения неавтоклавных конструкционно- теплоизоляционных пенобетонов, предназначенных для изготовления на их основе звукоизоляционных панелей, применяемых при устройстве межкомнатных перегородок.
Разработан состав неавтоклавного пенобетона марки по плотности D900 с классом по прочности на сжатие В3,5. Состав материала включает: портландцемент марки М500, грубомолотый речной песок, протеиновый пенообразователь и функциональные добавки.
Предложена технология изготовления панелей включающая отдельное приготовление растворной смеси и пены, их совмещение, формование массы и тепловую обработку в кассетных установках.
