The Effect of Composition on the Colloid Structure of Calcium Silicate Hydrate: Implications for Concrete Durability and a Basis for a Fundamental Understanding of Cement

将建立水化硅酸钙(C-S-H)的组成和结构之间的关系。C-S-H将被视为一种胶体材料，它已被成功地模拟为由半径约1纳米的粒子组成的一种组合物。它们聚集在一起，形成一种结构，显示出特定的表面积和密度，这取决于样品的大小，即探针的分辨率。中子散射和气体吸附为研究该结构提供了两种强大的技术。该模型将扩展到包括具有一系列成分的C-S-H，这些成分是通过化学控制产生的。

0070922JenningsThe relationships between composition and structure of calcium silicate hydrate (C-S-H) will be established. C-S-H will be treated as a colloidal material that has been successfully modeled for one composition as being made up of particles with about 1 NM radius. They are clustered together to make a structure exhibiting particular surface areas and densities that depend on the size of the sample, i.e. the resolution of probe. Neutron scattering and gas sorption provide two powerful techniques for investigating the structure. The model will be extended to include C-S-H with a range of compositions, produced through the control of chemistry.
