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 3/8". Occasionally aggregate with a top size of ¾" will be used. The most popular size is the 1 ¼" size. Both the 1" and 1 ½" size are relatively easy to make in the Texas Crushed Stone quarry. General
