Oct 28, 2013 · Some mix designs reach 5,000 psi of compressive strength in seven days – or even in 24 hours. However, the faster concrete reaches the minimum design compressive strength, the greater the cost of the concrete. Strength measurement protocol

Designing Concrete Inc. Designing Concrete can cut virtually any design in your concrete patio, walkways, pool deck, driveway, basement, etc. There are eight beautiful stain colors to choose from. The stain reacts with the minerals in the concrete to make a permanent color, resembling marble.Estimated Reading Time: 1 min

Initial Setting Time and Final Setting Time of Concrete. Reading time: 5 minutes. The initial setting time of concrete is the time when cement paste starts hardening while the final setting time is the time when cement paste has hardened sufficiently in such a way that a 1 mm needle makes an impression on the paste in the mould but 5 mm needle does not make any impression.

Concrete can set in less than two hours or can take as long as nearly 20 hours depending on conditions. Hot conditions provide the shortest setting times with a 100-degree day producing setting in about 100 minutes. Concrete exposed to temperatures just above freezing takes the longest at about 19 hours.

High early strength concrete (2500-3500 psi compressive in 24 hours) is usually accomplished using Type III high-early strength cement (see Table 1), high cement content (600-1000 lb/cu yd), and lower water-cement ratios (0.3 to 0.45 by weight). Super-plasticizers are also used to make the concrete mixture more workable during placement.
