are also very small. Atomization shears the water into very small particles, reducing surface tension and increasing the number of drops in a given area. Atomization is achieved by pumping water through nozzles at high pressure or by using a combination of compressed air and water pumped at lower pressure to produce very small drops or fog.

Before construction begins, simple laboratory tests establish the cement content, compaction, and water requirements of the soil material to be used. During construction, tests are made to see that the requirements are being met. Testing ensures that the mixture will have strength and longterm durability. No guesswork is involved.
The company is proclaimed for the manufacture, export, supply, distribution and wholesale of durable Cement Mill Water Spray System. These products effectively help cool off the cement mill operations due the large amounts of heat produced in such operations.
Sealing, painting, coating and cleaning of asbestos cement products. As a first priority removing asbestoscontaining material (ACM) must be considered. Where ACM cannot be removed and must be sealed, painted, coated or cleaned, there may be a risk to health. Such tasks can only be carried out on ACMs that are in good condition.

concrete is a composite material in which aggregates are bound in a porous matrix of hardened cement paste. At the microscale, the hardened paste is held together by bonds that develop between the products of the reaction of cement with water. Similar products are formed from the reactions between cement, water, and other cementitious materials.

Check for compatibility by applying a test patch of the recommended coating system, covering at least 2 to 3 square feet. Allow concrete to dry one week before testing adhesion per ASTM D3359. If the coating system is incompatible, surface preparation per methods outlined in ASTM D4259 are required.
The AAMA testing involves a calibrated spray nozzle that applies water at a known rate and pressure to very limited and specific areas. Less formal hose testing can be done on horizontal and vertical areas with similar results provided the water spray is controlled to wet only the areas intended to be tested.
A low pressure water spray* and a soft medium bristle (nonmetal) siding cleaning brush is most suitable for cleaning fiber cement products. NOTE: Acid and high pressure washing can damage the fiber cement surface and is not recommended. Clean James Hardie ColorPlus® products by using water and a soft brush or cloth.
