Description

374793 количество золы уноса. Затем производ т тщательное перемешивание грунта   золы, увлажн ют полученную смесь до оптимальной влайсности, после чего аологрунтовую смесь уплотн ют под давлением ЗО кгс/см. J 0 После трехмес чного хранени  в воз-. душно-влажных услови х приготовленных таким образом образцов зологрунтовой смеси, последние характеризуютс  высокими показател ми прочности и морозостойкости, значени  которых приведены в таблице.374793 amount of fly ash. Then, the ash is thoroughly mixed, the resulting mixture is moistened to an optimum area, after which the aologous ground mix is compacted under a pressure of 30 kgf / cm. J 0 After three months storage in the air. the air-humid conditions of the samples of the earth mineral mixture prepared in this way, the latter are characterized by high strength and frost resistance, the values of which are given in the table.

138 Зола уноса -25 Высока  морозостойкость и прочность зологрунтовой смеси достигаетс  без усложени  существующей технологии приготовлени  подобных смесей. Получаемые по известному способу материал после 6 сут выдержки в воде (содержание золы электрофильторов 2О% от массы грунта) имеет увеличение прочности при сжатии на 87%, коэффициент морозостойкости Кмрз составл ет 0,89 Были пригхзтовлены образцы из смесей с Гранойчнъш содержанием компонентов и испытань по целевым показател м. Согласно требовани м Инструкции по применению грунтов, укрепленных в жущими материалами дл  устройства оснований и покрытий автомобильных дорог и аэродромов (СН 25-74), материалы с такими свойствами могут быть использованы дл  создани  оснований дорог и аэродромов Т , и к m классов.138 Fly ash –25 High frost resistance and strength of the earth mineral mixture is achieved without complicating the existing technology of preparing such mixtures. The material obtained by a known method after 6 days of exposure in water (the ash content of electric precipitators 2O% by weight of the soil) has an increase in compressive strength of 87%, the frost resistance coefficient Kmrz is 0.89 The samples from mixtures with a Grain content of components were tested and tested target indicators. According to the requirements of the Instructions for the Use of Soils Strengthened with Stinging Materials for the Construction of Bases and Covers of Roads and Aerodromes (CH 25-74), materials with such properties can be used They are used to create the foundations of roads and airfields T, and K classes.
