Book Description
Consisting of silicates, iron and other compounds, slag cement is the by-product of molten iron production in a blast-furnace. Also known as ground granulated blast¬furnace slag, slag cement often used in concrete requiring maximum durability and higher strength. This study is to investigate the behavior of slag cement as a partial replacement material for Portland cement up to 30% and 40% of slag cement and its effectiveness in improving the properties of mortar. It was achieved by compression test and flexural test conducted to determine the highest strength development between samples for 7, 14 and 28 age days of curing time. There were three types of samples that has been tested according to BS 4551: Part 1: 1998, which are mortar containing 30% of slag cement, 40% of slag cement and mortar with plain ordinary Portland cement as the control samples. At the age of 28 days of curing, mortar containing 30% and 40% of slag gave compressive strength of 5.945 MPa, 11.51 MPa for air curing and 6.076 MPa, 12.34 MPa for water curing respectively and gave flexural strength of 2.2 MPa, 2.384 MPa for air curing and 2.249 MPa, 2.549 MPa for water curing respectively. Besides, this studies also to investigate the effect of curing condition to strength development and drying shrinkage of samples containing 30% and 40% of slag, where samples with water curing achieved higher strength development and low shrinkage rate than the samples with air curing. The used of concrete as samples besides mortar is recommended for future works and studies. -Author.

Book Description
This paper studies the effect of slag cement to the properties of mortar such compressive strength, flexural strength, workability and drying shrinkage. From the compression and flexural test, it was found that the increase in strength by time goes achieved at 70 percent replacement, even though it was still lower than control mortar. However the strength achieved for both sample was not differ too much where the strength was 13.41 MPa and 16.46 MPa in compression and 0.99 MPa and 1.21 MPa in flexural for curing in air and water respectively at 70 percent replacement while control mortar gave 20.82 MPa and 20.54 MPa compressive strength and 1.62 MPa and 1.56 MPa flexural strength for curing in water and air respectively. At aged 7 days, mortar containing 80 percent slag cement gave the highest flexural strength, 1.32 MPa but from whole results in both strength tests, the strength was reduced by the time goes. The strength achieved was only 0.69 MPa and 0.52 MPa in flexural and 5.82 MPa and 5.25 MPa in compression for water and air curing respectively. In drying shrinkage, it was found that mortar incorporating slag cement gave the greater results than control mortar but at 80 percent replacement in air curing condition, the shrinkage was obviously decrease and lower than control mortar at aged 13 days and beyond. Therefore from all of the strength achieved, it proved that the 70 percent replacement is more suitable to be used as cement partial replacement. -Author.

Book Description
This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet’s total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders Considers performance in adverse environmental conditions. Offers equal emphasis on the science behind the technology and its use in civil engineering.

Book Description
Cement-Based Composites takes a different approach from most other books in the field by viewing concrete as an advanced composite material, and by considering the properties and behaviour of cement-based materials from this stance. It deals particularly, but not exclusively, with newer forms of cement-based materials. This new edition takes a critical approach to the subject as well as presenting up-to-date knowledge. Emphasis is given to non-conventional reinforcement and design methods, problems at the materials' interfaces and to the durability of structures. High strength composites and novel forms of cement-based composites are described in detail. After a basic introduction the book explores the various components of these materials and their properties. It then deals with mechanical properties and considers characteristics under various loading and environmental conditions, and concludes by examining design, optimization and economics with particular emphasis on high-performance concretes. Researchers, graduate students and practising engineers will find this book valuable.

Book Description
Advanced cementitious composites can be designed to have outstanding combinations of strength (five to ten times that of conventional concrete) and energy absorption capacity (up to 1000 times that of plain concrete). This second edition brings together in one volume the latest research developments in this rapidly expanding area. The book is split into two parts. The first part is concerned with the mechanics of fibre reinforced brittle matrices and the implications for cementitious systems. In the second part the authors describe the various types of fibre-cement composites, discussing production processes, mechanical and physical properties, durability and applications. Two new chapters have been added, covering fibre specification and structural applications. Fibre Reinforced Cementitious Composites will be of great interest to practitioners involved in modern concrete technology and will also be of use to academics, researchers and graduate students.
