Використання відходів видобування гранітного каменю для виготовлення тротуарних бетонних виробів

Abstract

Existing directions of processing the screening dust of stone crushing plants, mainly by using in concrete and asphalt concrete production in Ukraine do not allow a significant waste utilization. Using the washed screening dust in the production of sidewalk unreinforced concrete wares, including sidewalk tile is promising and suitable for plants, in case of constructing the processing line at the enterprise since the demand for this type of products has increased in recent years. Laboratory tests on determining the controlled parameters of sidewalk tile samples, such as compression strength of concrete products, tensile strength in bending, wearability, frost-resistance, and water absorption have shown its compliance with Ukrainian quality standards. The widespread introduction of producing sidewalk tile with the screening dust content of more than 40% will lead to considerable reduction of the negative effects of accumulated waste on the environment, in particular, release land under heaps, expand the enterprise work scope and reduce dustiness of atmospheric boundary layer.

В работе приведены результаты, полученные при исследовании возможности использования отсева гранитного щебня в качестве заполнителя для бетонных тротуарных неармированных изделий, в частности тротуарной плитки. Определены прочность бетона изделий на сжатие, прочность на растяжение при изгибе, истираемость, морозоустойчивость, водопоглощение. Гарантировано получение строительных изделий повышенной прочности и надежности.

В роботі приведені результати, отримані при дослідженні можливості використання відсівів гранітного щебеню в якості заповнювача для бетонних тротуарних неармованих виробів, зокрема тротуарної плитки. Визначені міцність бетону виробів на стиск, міцність на розтяг при згині, стираність, морозостійкість, водопоглинання. Гарантовано отримання будівельних виробів підвищеної міцності та надійності.
