Cement Manufacturing

(a) Commercial Scale Carbon Capture at US Plant
LafargeHolcim, Svante Total and Occidental subsidiary Oxy Low Carbon Ventures (OLCV) will evaluate the cost of the carbon-capture facility, which is expected to capture up to 725,000 tonnes of carbon at LafargeHolcim Portland Cement Plant in Florence, Colorado. Read more.

(b) Importance of Conveyor Belting Basics
A conveyor belt failure can bring an aggregates operation to a standstill, which is frustrating because the cost of downtime is expensive. Trucks hauling product to you can’t unload, and the conveyors ahead of you are forced to stop and wait until the belt is repaired or replaced. Read more.



Concrete, Mineral and Chemical Admixtures



(a) Depleting Reserves Threaten Global Sand Demand
Shrinking availability of sand will be the primary factor restraining global demand growth, according to newly-published research on the global construction aggregates market from Freedonia GroupSupply constraints and higher material prices for virgin sand will continue to shift consumer preference toward crushed stone and secondary substitutes globally. Read more.

(b) Good Vibration is Key to Quality Concrete
Internal vibrators, sometimes referred to as “spud” or “porker” vibrators are the most common tools used to achieve concrete consolidation in foundations, columns and walls. In addition to consolidating freshly placed concrete and ensuring concrete completely flows into corners of the formwork and around reinforcement, vibrators blend different concrete lifts together into a single solid mass of concrete and minimize surface voids (bug holes) and lift lines on exposed concrete surfaces. Read more.

(c) Photovoltaic Elements in Concrete Facades
Researchers in Germany have developed a solar facade with photovoltaic elements they claim deliver up to 50% more solar energy than conventional, planar-mounted solar modules. The researchers have also demonstrated the feasibility of three different ways to mount photovoltaic elements on carbon-concrete facades. The three-meter prototype consists of nine panels based on an aluminum compound. The PV elements of the facade can be tilted to capture more sunlight. Read more.



(d) NIST Tests Could Lead to Stronger Building Codes, Improved Design Tools                                                                                                          The results of this study reported in the Journal of Structural Engineering, indicate that structures built to code are not always equipped to survive the forces induced by extreme shifts in temperature, but the data gained here could help researchers develop and validate new design tools and building codes that bolster fire safety.

(e) Electric Truck Mixers
Liebherr and Designwerk have developed fully electric truck mixers with 10 and 12 m³ drums on a 5-axle chassis. 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.
