Studies have shown that this thermal stability coupled with limestone’s superior curing properties results in greater crack spacing, and less crack width in limestone concrete slabs. Most concrete is made by mixing a ¼” to 200 mesh (200 wires per inch) sand with aggregate graded from 1 ½” to 3/8” or aggregate graded from 1 ¼” to 3
