Study on Microstructure and Rheological Properties of Cement-Chemical Admixtures-Water Dispersion System at Early Stage by Yanrong Zhang Pdf

This thesis studies the effects of superplasticizers, polyacrylate latexes and asphalt emulsions, which differ in molecular/particle size from nanometers to microns, on the rheological properties of fresh cement pastes (FCPs), as well as the action mechanisms involved. It systematically investigates the rheological properties and microstructure of cement-based materials, and elucidates the adsorption behaviors of polycarboxylate polymers with different functional groups and their effects on cement hydration. Moreover, it reveals how the working mechanism of naphthalene sulfonate formaldehyde (NSF) differs from that of polycarboxylate ether-based (PCE) superplasticizers. Lastly, it develops a conceptual microstructure model and two rheological equations. These findings lend theoretical support to the development of new chemical admixtures and new, higher-performance, cement-based composites.

Rheology of Fresh Cement-Based Materials by Qiang Yuan,Caijun Shi,Dengwu Jiao Pdf

This book introduces fundamentals, measurements, and applications of rheology of fresh cement-based materials. The rheology of a fresh cement-based material is one of its most important aspects, characterizing its flow and deformation, and governing the mixing, placement, and casting quality of a concrete. This is the first book to bring the field together on an increasingly important topic, as new types of cement-based materials and new concrete technologies are developed. It describes measurement equipment, procedures, and data interpretation of the rheology of cement paste and concrete, as well as applications such as self-compacting concrete, pumping, and 3D printing. A range of other cement-based materials such as fiber-reinforced concrete, cemented paste backfills, and alkali-activated cement are also examined. Rheology of Fresh Cement-Based Materials serves as a reference book for researchers and engineers, and a textbook for advanced undergraduate and graduate students.

Chemical Admixtures for Concrete by Ameer A. Hilal,Manhal A. Jibrael Pdf

Concrete, a construction material, is widely used because of its excellent properties such as durability, workability, satisfactory strength, and the easy availability of raw materials (cement, aggregates, and water), which are used to produce it. In recent years, the demand for ready-mix concrete (RMC) has increased rapidly. The primary reasons behind this are convenience of using RMC in high-rise structures, shortage of space at construction site, saving of time related to the preparation of concrete on-site, and better quality of RMC compared to the conventional concrete. To produce a concrete with specific requirements such as high performance concrete (HPC), additives and admixtures are added to raw materials of normal concrete to improve some properties by pozzolanic and physical actions. Nowadays, the concrete admixtures are widely used in the construction projects. The main types of chemical admixtures can be summarized as plasticizers, accelerating/retarding agents, air entraining agents, waterproofing additives and others such as corrosion inhibitors and coloring agents etc. The benefits derived from the use of chemical admixtures include improved durability, strength, chemical resistance, coloring, reduction in water and cement requirement and enhanced working properties of concrete. These admixtures improve the concrete microstructure by making it denser, more homogeneous, and uniform, leading to enhance its properties such as strength and durability compared to the plain mix. Chemical Admixtures for Concrete covers the theory and real world cases to understand the effects of different types of chemical admixture on properties of concrete. Effects of different chemical admixtures on fresh and hardened properties of prolonged mixed concrete and their cost-effectiveness were investigated. Influence of sand to aggregate volume ratio, cement content, and use of chilled mixing water on the properties of prolonged mixed concrete was studied as well. Presenting information on the materials, hydration, and the strength and durability of cement and concrete with mineral admixtures; this book will appeal to practicing engineers and students alike.

Admixtures for Concrete - Improvement of Properties by E. Vazques Pdf

Chemical admixtures are used to modify the properties and behaviour of fresh and hardened concrete. They enable more economic construction and the achievement of special properties such as high strength or durability. This book presents new research information from an International RILEM Symposium on six main topics: workability, setting, strength, durability, other properties and technology.
