The correct answer is: C. 300 kg\/cm2<\/p>\n
The compressive strength of concrete is the maximum stress that a concrete can withstand before it fails. It is usually measured in kilograms per square centimeter (kg\/cm2). The compressive strength of concrete is affected by a number of factors, including the type of cement used, the water-to-cement ratio, the aggregate type and size, the curing method, and the age of the concrete.<\/p>\n
In favorable circumstances, a 15 cm concrete cube after 28 days, attains a maximum crushing strength of 300 kg\/cm2. This means that a concrete cube with a side length of 15 cm can withstand a compressive load of 300,000 kg before it fails.<\/p>\n
Option A is incorrect because the compressive strength of concrete is typically much higher than 100 kg\/cm2. Option B is incorrect because the compressive strength of concrete is typically much higher than 200 kg\/cm2. Option D is incorrect because the compressive strength of concrete is typically much higher than 400 kg\/cm2.<\/p>\n","protected":false},"excerpt":{"rendered":"
