The design of concrete mixes is becoming increasingly complex, with the addition of new materials in the compounds, such as organic admixtures, fibres and supplementary cementitious materials. Moreover, the list of properties which concretes are required to possess for certain applications has increased, and interest is developing in rheology, durability, deformability and whole-life behaviour. This book presents a number of simple models for the understanding of a concrete system, and provides the techniques for developing more sophisticated models for the practical design of concrete mixes.

India can be a more favorable and attractive industrial area for the development of granite industry now a days and in future. India has been known for decades for its stone industry and it is one of the biggest exporters of natural stone in the world. India uses natural stone as building material more than many other countries. The researcher explores whether Indian granite industries can increase their exports to world countries and how likely it is that stone imports will increase there. Each country has unique soil and granite stones. Granite from India is very different compared to world granite and it cannot be copied. The unique appearance of Indian granite is definitely a competitive advantage that should be considered when planning export strategies.

There is no substitute for concrete that can be used on the same engineering scale. Its sustainability, exploitation and further development are necessary for a healthy economy and environment worldwide. Concrete must keep evolving to satisfy the increasing demands of all its users.
This project was designed to explore the feasibility of lowering the cementitious materials content (CMC) used in Wisconsin concrete pavement construction. The cementitious materials studied included portland cement, fly ash, and ground granulated blast furnace slag. For the first phase, mixtures were prepared using the current WisDOT aggregate grading specification. For the second phase, mixtures were prepared using an optimized (e.g. Shilstone) gradation. A variety of tests for fresh and hardened concrete were conducted to determine the viability of low CMC mixtures for use in concrete pavement.
