Gravel comes in a wide variety of forms, but the three basic types of gravel for driveways are crushed stone, pea gravel, and river rock. Crushed stone: Most people think of crushed stone when they think of Generally, sand and gravel consist of an unconsolidated accumulation of rounded or semi-rounded rock fragments that result from the natural disintegration of rock (see entry on Weathering ). Sand and gravel can be described in terms of texture and composition. Texture refers to the size of grains, size sorting, and shape of grains.Sand and gravel resources SpringerLink

Sustainable use of different wastewater in concrete construction:
The use of reclaimed wastewater suggested that this water could be used in making concrete without any dangerous effects. The 28 days compressive strength of specimens made with reclaimed wastewater increased to 8%–17% with 25%–100% use of reclaimed water [13]. However, the consumption of wastewater in mixing and curing of 1 part cement. In an ideal world, where everything is delivered dry, a water to cement ratio of approximately 0.55 should be used. As we have explained above, if requiring 25kg of cement in your mix, then to calulate the suggested volume of water it would be: 25 x 0.55 = 13.75kg (litres) of water.Concrete Mix Ratio and How to Mix Concrete DIY Doctor

Washed Aggregates BoDean
Washed aggregates are simply aggregate material that has undergone the wash process to remove dirt, or any other matter by applying a heavy force of water. More simply put, this is the process of washing clay, dirt and debris off of the rock once the aggregate has been mined.

How To Find The Right Pressure For Washing Exposed Aggregate Concrete
To effectively clean concrete, use a power washer with a pressure rating of at least 3000 psi and a flow rate of at least 4 gallons per minute (gpm). If you’re cleaning concrete, you’ll want to use a pressure washer that has a maximum pressure of 3000 pounds per square inch.Mix the gravel around to get the cleaner on all surfaces and allow to sit for one to two minutes. Run warm water through the gravel to rinse away the dirt. The gravel and any larger debris will be caught in the colander while the dirt, carrying the bulk of the dirt with it, will wash away. Use an empty five-gallon bucket to wash larger quantities.How Can I Wash Pea Gravel? HomeSteady
