Abstract:

A fundamental understanding of the nano-structure of Portland cement concrete (PCC) is the key to realizing significant breakthroughs regarding high performance and susta ; (MBTC 2095/3004) using molecular dynamics (MD) provided new understanding of Calcium Silicate Hydrate (CSH) structure (the main component giving strength and dur ; limited, particularly regarding nano-level mechanical properties in the PCC due to number of atoms that could be considered in the MD approach. In this work discrete elem ; CSH gel structure is proposed. The progress made in phase I out of three phases is reported. The review of DEM application in engineering and specifically for CSH study is ; commercial code available for DEM study is presented. An in house DEM code is developed to apply an indentor type load to a cohesive material. Sample model calculation ; and application of the DEM code.
