The choice from the above sizes depends upon the dimen- sions of the concrete member more particularly, the spacing of the steel bars reinforcement or as specified. This is. Workability 3.
Durability 2. Strength 4. The water cement ratio is first determined at the very first hhour of mixing to meet the requirements of strength and durability 2. Laboratory tests showed that the water-cement content ratio Is the most important consideration in mixing because it deter- mines not only the strength and durability of the concrete but also the workability of the mixture. Fresh concrete shall be workable. That, the hardened concrete shall be strong enough to carry the design load.
That, concrete should be economically produced. Concrete Mixture may be classified as either: a. Designed Mixture 'b. Prescribed Midture Designed Mixture.
Where the contractor Is responsible in establishing the mixture proportion that will achieve the required strength and workability as specified in the plan. Prescribed Mixture. Where the designing engineer specify the mixture proportion.
The contractor's responsibility is only to provide a mixed concrete containing the right propor- tions as in the plan. Lately however, under the SI measures, the 94 pounds per bag cement equivalent to Recently added sections include: Restorative drying, water damage and mold remediation.
