Keywords: lime, mortar, reaction kinetics, microstructure, numerical simulation And use as input to upscale to meso-, macro- scale of Lime-mortar. In the end a comprehensive microstructure of lime mortar can be obtained, including the pore structures, pore solution chemistry, crystal phases and amorphous phases.Įxpected Results: to produce a framework for simulating the chemical reaction and microstructural development of lime-based materials.
Based on the reaction kinetics model developed above, the physical and chemical process, i.e., the dissolution, nucleation and growth of lime will be simulated by coupling ion transport and thermodynamics, where Lattice Boltzmann methods will be employed to deal with ions transport, while Phreeqc will be employed to simulate the chemical reaction and thermodynamics. In the kinetics model the volume fraction of reaction production (mainly calcium hydroxide), unreacted lime and capillary pores will be simulated explicitly. The focus will be mainly in the development of reaction kinetics model which will consider the chemical composition of lime, liquid to powder ratio and reaction temperature.
The generated microstructures will be used as input for predicting the physical and transport properties of lime-based materials, and act as a tool for designing new generation of sustainable/functional lime mortars/plasters. Objectives: to build up a numerical model which can simulate the chemical reaction process, and microstructural formation of lime-based materials.
