∙ 11y ago
Sure you can, vertical and horizontal construction joints are allowed in the Raft with depth of 3.00 meters and above in hot countries , to avoid differential temprature between the core of cast and concrete temperature at the time of cast, the recommended depth should not exceed 1.5 with temperature control sensors and proper immediate curing

Does the amount of water in a gravel based concrete depends on how fast it will harden?
yes, because after casting, concrete will get its 90% strength within 28 days and proper hydration require the proper amount of water for atleast 28 days.
How is pre-stressed concrete made?
Pre-stressed concrete is made by using,high strength steel bars(tendons).normal concrete(>M25)sheaths for cable duct.anchors.jacks.

What are the classifications of continuous casting machines?
Continuous casting machine can be classified according to a variety of forms. If according to the structure appearance can be divided into vertical continuous casting machine, vertical bending continuous casting machine, with straight section arc continuous casting machine, arc continuous casting machine, multi-radius oval continuous casting machine and horizontal continuous casting machine. With the development of continuous casting technology, and carried out the wheel type continuous casting machine, especially the thin slab continuous casting machine research.

What is C25 concrete?
C25 concrete is a concrete having compressive strength of 25MPa when tested at the 28th day after casting. The specimen can be cube(150x150x150) or cylindrical(125mm by 250mm high). The cube strength has 0.8 times that of cylindrical specimen due to shape factor.
