Influences of Latex and Mixing Procedure on Mechanical Properties of Hardened Cement Paste(II)


Article Preview

In this study,influences of latex and mixing procedure on flexural strength, compressive strength, elastic modulus and apparent fracture energy of hardened cement paste mixed with polycarboxylate (PC) as superplasticizer were analyzed. The results show that, the apparent density of fresh latex modified cement paste (LMCP) and the compressive strength of the hardened LMCP were reduced 1%-8% and 0-28% respectively compared with the control, while the flexural strength and apparent fracture energy were increased 11%-70% and 22%-157% respectively. In generally, the mixing procedure had gentle effect on the mechanical properties of harden LMCP with the same mp/mc, while the different mp/mc and latex types had greater impact. The amounts of polymer adsorbed changed by mixing procedure and had significantly effect on the properties fresh LMCP while very little on the harden LMCP.
