ASTM C109

ASTM C109 is a standard test method used to measure the compressive strength of hydraulic cement mortars. In simpler terms, it helps determine how much pressure a mortar mix can withstand before it breaks. This test is important for ensuring that the materials used in construction, like those in buildings and pavements, are strong and durable. The process involves mixing specific ratios of cement, sand, and water, forming samples, and then applying increasing pressure until failure occurs, allowing engineers and builders to assess the suitability of the mortar for various applications.
