  • Compressive Strength Test of Concrete

     · Compressive strength as a concrete property depends on several factors related to quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common]. For example, as per ASTM C39, a standard test method is given to get the .

    Aug 06, 2017 · Concrete strength varies with time, and the specified concrete strength is usually that strength that occurs 28 days after the placing of concrete. A typical strength–time curve for normal stone concrete is shown in Figure 2. Generally, concrete attains approximately 70% of its 28day strength in 7 days and approximately 85% to 90% in 14 days.
