Exploration for the Technology of Tradition Building Materials and Consolidation Mechanism

Abstract:

In this paper, we exploded the technology of Sanhetu based on the historical records and previous studies. Mixing technology, molding pressure, W/S, curing time and curing method were investigated to increase the compressive strength of the imitating samples. XRD, FTIR and SEM were used to analyze the composition and consolidation mechanism. The results show that the compressive strength of the imitation could exceed 50 MPa, when molding pressure is 20 MPa, W/S is 0.49 with mixing technology A. Pozzolanic reaction is significant in strength development. And the reaction product, CSH gel, is the main factor in strength gain. Sufficient inner water of the imitating samples could contribute to the pozzolanic reaction. And increasing temperature could accelerate the reaction. The study confirms the possibility of the imitation for Sanhetu.
