How to use
- Batching and mixing of mortar & concrete shall be carried out with a pre-determined mix design. In preparing concrete or mortar mixes, proportioning of constituents are measured by either weight or volume. Readymixed or plant-mixed concrete are normally designed by weight, while site-mixed or manual applications are typically done by volume, to control constancy of results that should satisfy project requirements.
- Concrete shall be placed to its final position before initial setting has started and shall not be successively disturbed. In many types of construction, concrete is placed into the forms and then consolidated by means of compaction. Consolidation densifies concrete within the forms, around reinforcements and embedded items. Proper compaction is usually conducted to avoid honeycomb and entrapped air.
- To produce a desired surface appearance, finishing operation should be carefully planned. It should be conducted on a proper timing considering weather condition and concrete setting time. Follow standard procedures on concrete finishing using appropriate tools and equipment.
- As to all concrete, proper curing is essential to achieve the desired concrete properties. Typical concrete curing practice allows a minimum of 7 days curing period. Maintaining concrete in a moist condition using water sprinklers or spray, covered with wet burlap and/or polyethylene sheets, curing compounds coating and other water retaining techniques.
