This book redefines concrete as a moisture-responsive, porous material, revealing how cement-based materials interact with water through their nanoscale pore structure. This transforms our understanding of dimensional stability, long-term durability, and other aspects of concrete science.Using low-field nuclear magnetic resonance relaxometry, the author non-destructively characterizes the in-situ nanoscale pore structure of white cement-based materials and uncovers how it evolves with water content. The author identifies “water sensitivity” — the wetting expansion and drying contraction of calcium silicate hydrate — as the mechanism behind this behavior, analogous to clay minerals. The water sensitivity theory is validated by the microstructural characteristics of the dynamic pore structure, including a layered structure with a large specific surface area and a negative surface charge, and is substantiated by experimental results on permeability and sorptivity. Building on this framework, the book reexamines the effects of the water-to-cement ratio and curing temperature on the pore structure and water permeability of cement mortars. The book also successfully models phenomena, including deviated long-term water absorption, the anomalous dependence of sorptivity on initial saturation, and the isothermal drying of cement-based materials.This book will serve as an essential reference for concrete scientists, materials engineers, and researchers studying the dimensional stability and long-term durability of cement-based materials, as well as their many other moisture-regulated performances.

Scarcity hypothesis is the cornerstone of traditional economic theory. However, in the digital era, new products such as Windows, Android, and Wechat have been introduced to the market. Traditional economic theory may not be able to explain various nez economic phenomena in the digital era. This book creatively proposes the concept of limitless supply and then discusses its implications for economy at both macro and micro-levels.It analyses and summarizes the basic features of limitless supply products, and compares the differences and similarities of how limited supply and limitless supply products are manufactured and marketed. The book also provides reasons for why manufacturers of limitless supply products create intangible assets. It argues that the scale of an enterprise producing limitless supply products depends on the number of users, whereas the scale of an enterprise producing limited supply products depends on the production capacity.This book is mainly written to construct a preliminary, simple, yet relatively comprehensive economic theory framework for limitless supply, and to interpret the phenomena and corporate behaviour. It further explores how enterprises providing limitless supply products grow financially. It also proposes the fundamental difference in growth models between enterprises providing limitless supply products and those providing limited supply products. The book also looks at how growth models can achieve fission growth.

This book is the first of its kind in providing, simultaneously and comprehensively, historical, institutional and theoretical foundations for developments in the stock market. It debunks many a myth about stock price behavior and the valuation of stocks. The traditional valuation models are tested and shown to be often weak and unreliable, especially when applied to the valuation of technology stocks. New paradigms are suggested.The authors seek to answer many questions about the stock market: Why invest in stocks, how to invest in stocks, how to value stocks, how to change the risk profile of portfolios, how to analyze the results of stock investing, and how to minimize estate taxes and maximize control, even after death.All aspects of the stock market are covered, including the basic tools that will enable the reader to understand the stock market basics, the history of stock market performance in the US and overseas, the various ways to value stocks and to assess their risk, and the various methods that have been proposed to capitalize on the inefficiencies of the stock market, be they temporary or permanent. The book also deals with the derivative markets for stocks.
