Virtual Cement and Concrete Testing Laboratory: Version 9.5 User Guide

Abstract

This document serves as the user’s guide for the Virtual Cement and Concrete Testing Laboratory (VCCTL) software, version 9.5. Using the VCCTL software, a user may create 3D microstructures of cement paste made with clinker, calcium sulfate, fly ash, slag, limestone, and other materials. Hydration of these microstructures can be simulated under a variety of curing conditions, and the resulting hardened material can be analyzed for a number of properties including linear elastic moduli, compressive strength, and relative diffusion coefficients. A 3D packing of fine and coarse aggregates in mortar and concrete materials also can be created. The VCCTL software uses a relational database and plotting capabilities to facilitate viewing important characteristics of cement powders, supplementary cementitious materials, fillers, and aggregates.
