Compressive Test Some Concrete Specification Requires The Compressive Test Strength for Both 7 Days and 28 Days. Why? 7-day compressive strength test results are usually not used for acceptance purpose but for information only. Instead, 28-day compressive strength test results are commonly adopted for acceptance purpose. 7-day compressive strength test results are often used to […]

Super Pave Mix Design Method What is super pave? In the 1980s, many state transportation departments were experiencing widespread premature deterioration of asphalt pavements. To address this problem the Strategic Highway Research Program (SHRP) undertook a program of asphalt research that eventually led to a new asphalt mixture design and analysis system called Super pave. […]

Concrete Test Equipment Concrete Test Equipment is a building material that hardens over time by mixing cement, fine aggregate (sand), and coarse aggregate with water. Portland cement is a type of cement widely used in concrete production. Concrete technology deals with the study of the properties and practical applications of concrete. In building construction, concrete […]
