Foreword

Portland cement concrete is the most widely used building material in the world. It plays an important role in infrastructure and private buildings’ construction. Concrete is basically made of filler and Portland cement. It is the hydration products of Portland cement that glue the individual particles of the filler together to form a solid material. Obviously, the mechanical property enhancement of concrete needs a deep understanding of the nature of hydration product. Especially, a quantitative understanding of calcium silicate hydrate (C–S–H), the most important hydration product, on the atomic to 100 nm scale is one of the most important, long-standing needs in cement science as it can be used to explain how to control the mechanical, transport, and chemical properties of hydrated cement paste. Fortunately, with the advancement in technology, a wide range of experimental and computational tools are available in recent decades for discovering the nature of hydrate of cementitious materials. The numerical si
