Abstract
Использование: производство строительных материалов, составы бетонных смесей с химическими добавками Сущность изобретени : бетонна смесь включает портландцемент 16,072-22,232%, заполнитель 66,667-76,391% фосфорсодержание соединени - диметилфосфмт в количестве 0,016- 0,129% или три(2-хлорэтил)фосфит в количестве 0,044-0,178% или три(2-хлорэ- тил)фосфат в количестве 0,044-0,133% и вода остальное. Прочность бетона после ТВО в возрасте 28 сут на сжатие 40,6 МПа, на изгиб6,16МПа 1 табл.Use: production of building materials, concrete mixtures with chemical additives -0.178% or three (2-chloroethyl) phosphate in the amount of 0.044-0.133% and water is the rest. The strength of concrete after TVO at the age of 28 days for compression is 40.6 MPa, for bending 6.16 MPa 1 tab.
Description
Изобретение касаетс строительных материалов, в частности составов бетонных смесей, используемых в производстве бетонных и железобетонных изделий и конструкций .The invention relates to building materials, in particular the compositions of concrete mixtures used in the manufacture of concrete and reinforced concrete products and structures.
. Цель изобретени - повышение прочности бетона на изгиб.. The purpose of the invention is to increase the strength of concrete in bending.
Бетонную смесь готов т по следующей методике, в начале перемешивают портландцемент М-500, гравий фракции 5-20 мм и речной песок с Мкр-1,18 при массовом отношении песка к гравию 0,537, а затем ввод т воду затворени с фосфорсодержащими добавками и полученную смесь перемешивают до получени однородной массы Тепловлажностную обработку бетонных образцов провод т по режиму: Зч + Зч + 8ч + Зч при 85°С.The concrete mix is prepared according to the following method, at the beginning Portland Cement M-500 is mixed, gravel is 5–20 mm and river sand with Mcr-1.18 at a mass ratio of sand to gravel is 0.537, and then the mixing water with phosphorus-containing additives and the resulting the mixture is stirred until a homogeneous mass is obtained. The heat and moisture treatment of concrete samples is carried out according to the following mode: Zch + Zch + 8h + Zch at 85 ° C.
