Years of cement production practice shows that cement particle gradation should be distributed continuously within a certain size range. Generally speaking, the cement particles smaller than 32 μm are beneficial to reduce bleeding and early strength, but as the size of particles gets smaller, although the hydration activity increases, the voidage of particles will also increase when they ...

Freshly poured concrete — especially low-slump concrete or another type with a less fluid mix — can have thousands of trapped air bubbles. If you left the concrete to settle on its own, these air bubbles would result in a phenomenon called honeycombing, in which weak spots cause instability. To avoid this result, …
