Unfortunately, concrete mix you get from the store will give you 3000 to 5000 psi compressive strength concrete maximum. You have to use special additives to make it high strength or durable under special ambient conditions like near sea.

Mineral admixtures affect the nature of the hardened concrete through hydraulic or pozzolanic activity. Pozzolans are cementitious materials and include natural pozzolans (such as the volcanic ash used in Roman concrete), fly ash and silica fume. They can be used with Portland cement, or blended cement either individually or in combinations.

The results of light weight concrete density with additives show significant density decreasing (from normal concrete) for rice husk than rubber cuttings, silica gel, wood sawdust,(Figuer- 6&7),(table-5).
Admixtures can work to alter the rate of heat generation but at the same time can result in lower concrete strengths. In mixes where low water/cement ratios are required for durability (such as bridges, parking structures or marine facilities), concrete is often substantially over-designed for strength.

Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens.
The use of retarding admixture has the main drawback of the possibility of rapid stiffening, where rapid slump loss will result in difficulty of concrete placement, consolidation, and finishing. An extended-set admixture has been developed as another retarding admixture.
