Ultrafine sand can be delivered with just the right amount of moisture so that it can be shaped on the jobsite. This will help it conform to the bottom of pools. Ultrafine sand works well as a sand base for swimming pools, a shaping sand for sandboxes and sandcastles, and a beach volleyball sand that is soft on the feet.
Particle size distribution - this test can be conducted at site or in laboratory for every 40 cum of sand. Bulking of sand – this test is conducted at site for every 20 cum of sand. Based on bulking of sand, suitable water cement ratio is calculated for concrete at site. 1. Test for Silt Content Test of Sand
The testing results on sand cement brick, including the density test, compressive strength, and water absorption test, are described in this chapter. An analysis was done according to the different percentages of RCA and CR as a partial replacement of NA in sand cement brick under curing conditions of 28 days, respectively.
Option 2: Water Absorption Test (Best for rain garden planning.) Perform the following infiltration test at each location selected for a potential rain garden. 1. Dig a hole 6 inches deep by 6 inches in diameter. 2. Fill hole with water and let stand for one hour. 3. Refill hole with water. Measure depth of water with a ruler. 4. Let stand 1 hour.
