Cement Hydration monitoring - MIT Admir Masic

Cement is the most widely used construction material and its demand in recent decades has increased exponentially. Cement is usually mixed with aggregates and water to form concrete. It is widely used in construction because it can be easily applied by being poured into molds (high fluidity) and can harden itself into a strong material over time (high strength).

Maturity Functions - Maturix Smart Concrete Sensors

2021-8-14  The standard definition is as follows: “A maturity function is a mathematical expression to account for the combined effects of time and temperature on the strength development of a cementitious mixture. The key feature of a maturity function is the representation of how temperature affects the rate of strength development.” (ASTM C1074)
