Abstract
Cement Sand and Gravel (CSG) is a new type of construction material between RCC and ordinary concrete. At present, there are few research theories on cemented sand and gravel in China. Therefore, this paper analyses the influence of unit cement content and aggregate maximum particle size on the compressive strength of cemented sand and gravel through experimental research. The test results show that the compressive strength has increased with the increase of unit cement content; the compressive strength of the material has a decreasing trend as the maximum particle size of the aggregate increases from 20mm to 80mm. The analysis of the test results shows that when the maximum particle size of the aggregate is 40mm and the unit cement content is above 80kg / m3, the compressive strength of the material can be guaranteed and the material can be used reasonably.
