Slow cooling in mineral formation promotes
Webb28 mars 2024 · Finally, the strength development of calcium silicate hydrate (C-S-H) gel formed by cement hydration is slow, leading to low early strength development of coral concrete, which causes the settlement of coral concrete after completion. It severely affects the filling effect. WebbBowen ’ s reaction series. Bowen ’ s reaction series describes the temperature dependent formation of common minerals as magma cools to form igneous rocks. The temperature of the magma and the rate of cooling determine which minerals can form and the size of the mineral crystals formed. The slower a magma cools, the larger crystals can grow.
