Cement Manufacturing 

(a) Reclaiming Fly Ash for Use in Cement Manufacturing                           The drying and electrostatic separation equipment allows for Brunner Island basin ash to be converted to ProAsh and EcoTherm without relying on high temperature combustion of the residual carbon. Read More.

Concrete, Mineral and Chemical Admixtures

(a) Investigating Concrete Cracks                                                            There are two basic types of concrete cracks: intrinsic or non-structural and structural. Intrinsic are naturally occurring cracks that are related to concrete as a material such as plastic settlement and shrinkage, freezing of freshly placed concrete, crazing, thermal and drying shrinkage, seasonal temperature changes, corrosion of reinforcement, and alkali-aggregate reactions. Whereas, structural cracks are typically associated with overloads from either construction or service loads. Read more.

 (b) Repairing Concrete Cracks                                                             Concrete structures crack as they age due to deterioration phenomena such as carbonation, chloride attack, and freeze–thaw. Cracks may also occur due to corrosion of steel reinforcements, which can rapidly degrade the structural integrity. Read more.

 (c) Radiation-Shielding Concrete                                                              High-fluidity and self-compacting concrete (SCC) mixes were developed using special aggregates for radiation-shielding concrete. The special aggregates comprised heavyweight and hydrous aggregates (crushed magnetite, crushed serpentine, and their mixtures), which were selected to provide an enhanced attenuation of gamma and neutron radiation, respectively. Read more.

(d) Wheat Straw Ash as Partial Sand Replacement for Production of Eco-Friendly Concrete

Environmentally friendly solution is proposed to investigate the incorporation of wheat straw ash (WSA) by replacing fine sand in concrete. Read more.

(e) Plastic Waste to Build Better Radiation Shielding                    Researchers added powdered plastic waste to concrete and improved its radiation shielding capacity. Read more.

(f) Longest Prestressed Girder                                                                    The Washington State Department of Transportation teamed up with Concrete Technology to produce the longest prestressed girder of more than 223 feet for a bridge over the Puyallup River. Read more.

 (g) Ground Penetrating Radar for Concrete                                      Traditional methods for determining the strength and resilience of concrete in aging structures are costly and require precise data collection. A new study finds merit in a less costly and nondestructive alternative using ground-penetrating radar on concrete bridges to trace differences in compressive strength along decks. Read more.

 

Books

(a) Mineral Admixtures in Cement and Concrete, Author: Jayant D. Bapat, CRC Press, Taylor & Francis Group 

Written for engineers, this book focuses on how to make more workable and durable concrete using mineral admixtures. For each mineral admixture, the book looks at manufacturing and processing, physical characteristics, chemical and mineralogical composition, quality control, and reported experiences. It also examines the provisions of national standards on the admixture’s addition to cement and concrete. Offering a deeper understanding of mineral admixtures, it encourages engineers to more effectively use these and other wastes in cement and concrete to support more sustainable growth of the cement and construction industry. Read More.

 

(b) Blissful Souls All Of Us: Author: Dr Jayant D Bapat: Publisher: CreateSpace, USA. 

The Book is a result of author's quest to remain happy forever. It focuses on self-improvement through meditation. The real and original nature of self, common to all human beings, is empathic, pure and joyful. However, that ‘self’ has deviated considerably from its original nature. Meditation is a time-tested tool to reach the original nature of self. Like exercise is for the body, meditation is for the mind. Practice controlled breathing or pranayam to assist meditation. The book gives helpful tips to practice meditation for self-improvement. Blissful experiences gained during meditation are useful resolving conflicts, reducing stress, building durable personal relationships and recording improved performance at the work. Meditation and controlled breathing balance the intelligence. The exercise teaches to take a holistic view of life and life’s problems. Book is available in both print and Kindle version.
