Capillary Absorption of Liquid by Powder Compact and its Application on Preparation of Repeatable Cement Compacts

Abstract:

Preparation of repeatable cement compacts may contribute to quantitively research of processing, structure and properties of cement materials. Capillary absorption of liquid by powder compact was briefly reviewed. Deviation degree of absorption coefficient (Dac) was designed for evaluation on repeatable preparation of cement compacts. Dry cement was compacted in special moulds. A group of orthogonal experiments were designed to investigate repeatable preparation of the compacts. Results show the most important factor influencing on repeatable preparation is the cavity size of mould. The influence of force and specific surface area of cement is generally below 1.41%. According to optimum scheme for preparation, Dac is 0.00%. Repeatable preparation of cement compacts may provide a new method for quantitatively research of cement materials.
