Mesoscopic Numerical Computation of Compressive Strength and Damage Mechanism of Rubber Concrete

Table 2

Number of rubber particles under different rubber content.

Specimen	Content of rubber (kg/m^3)		Diameter of particles (mm)					Number of
			27.5	22.5	17.5	12.5	7.5	2 mm rubber particles
NCR0	0	0.74	2	3	7	18	66	—
NCR10	27.7	0.74	2	3	7	18	66	68
NCR20	55.4	0.74	2	3	7	18	66	138

Note: the meaning of the specimen designation (e.g., NCR10) is as follows. NRC is crumb rubber concrete, and the number 10 means that the rubber content is 10% (volume of sand-size fraction).
