Abstract
Изобретение относитс к промышленности строительных материалов, может быть использовано при производстве бетонных и железобетонных изделий и направлено на повышение трещиностойкости. Песок перед смешением с цементом и водой обрабатывают в водном растворе перманганата кали 0,5 - 1,0%-ной концентрации в течение 30 - 60 мин и прокаливают при 600°С в течение 30 - 60 мин. Трещиностойкость составл ет 0,18. 1 табл.The invention relates to the building materials industry, can be used in the manufacture of concrete and reinforced concrete products and is aimed at improving the crack resistance. Before being mixed with cement and water, the sand is treated in an aqueous solution of potassium permanganate of 0.5–1.0% concentration for 30–60 min and calcined at 600 ° C for 30–60 min. Crack resistance is 0.18. 1 tab.
Description
Изобретение относитс к производству строительных материалов и может .быть использовано при производстве бетонных и железобетонных изделий.The invention relates to the production of building materials and can be used in the manufacture of concrete and reinforced concrete products.
Целью изобретени вл етс повышение трещиностопкости бетона.The aim of the invention is to increase the fracture toughness of concrete.
Пример. Тщательно перемешивают песок (1500 г), предварительно обработанный раствором перманганата кали и цемент (500 г), после чего сухую смесь затвор ют водой. Песок обрабатывают выдержкой в 0,5%-ном растворе КМп04 в течение 1 ч при соотношении песка и раствора 1:1 с последующей прокалкой при 600 С в течение 30 мин.Example. Sand (1500 g), pre-treated with potassium permanganate solution and cement (500 g) are thoroughly mixed, after which the dry mixture is sealed with water. The sand is treated with a 0.5% KMp04 solution for 1 h at a ratio of sand and 1: 1 solution, followed by calcining at 600 ° C for 30 minutes.
В таблице представлены результаты испытаний образцов 4x4x16 см, изготовленных на морском песке, обработанном раствором КМп0.д из бетоннойThe table presents the results of testing samples 4x4x16 cm, made on sea sand treated with KMn0.d solution of concrete
смеси состава 1:3. Испытание образцов на сжатие и изгиб производ т в соответствии с ГОСТ 310-76.1: 3 mixtures. Test samples for compression and bending produced in accordance with GOST 310-76.
Оптимальное врем обработки от 30 мин до 1 ч. Дальнейшее увеличение времени обработки не вли ет на прочность бетона.The optimum treatment time is from 30 minutes to 1 hour. A further increase in the processing time does not affect the strength of the concrete.
