Concrete, Mineral and Chemical Admixtures

(a) Wood as Aggregate in Concrete
Researchers in Switzerland have taken the modern approach to using both wood and concrete for building one step further and are using wood as the aggregate in concrete. Stress tests on the load-bearing concrete with more than 50% wood has yielded positive results for wall, slab and structural elements. Read more. 

(b) Robotics in Construction
Robotics in use in the field today is helping to pave the way for future builders by showing the technology's potential to aid productivity and eliminate rework. Read more.

(c) Rigid Concrete Pavement is more Flood Resilient
Road authorities should consider changing their roads to flood-resilient pavements in the future. Read more.

(d) Carbon Fiber Strips to Strengthen Bridges
The Arizona Department of Transportation has used what it calls "a space-age technique" to repair and strengthen concrete girders on two freeway bridges in Phoenix. Read more.

(e) World's Tallest Roller-Compacted Dam
The 318-foot tall dam — the tallest built using a new concrete construction process  — nearby Lake Hodges pump station, 11-mile San Vicente Pipeline and newly raised San Vicente Dam can together store six months of water supply in case the region is cut off from Colorado River aqueducts. Read more. 

(f) Precast Concrete Blends Tradition with Contemporary Design
Over 250 precast concrete components were produced for the project, including precast concrete panels, beams and arched spandrels. Precast concrete wall panels provide both load-bearing structural capabilities and the desired architectural finish for this house of worship. Read more.

(g) Offsite Construction: Current Trend
Increasing collaboration between off-site manufacturers and contractors is the biggest among five trends in construction. Read more.

(h) First Commercial Building Project to Use 3D Printing
Crossrail in London is the first commercial building project to use 3D printing. Read more.

(i) Seven Steps to Boost Productivity in Construction Sector
McKinsey research finds seven levers can fix construction’s productivity problem, but they require a new approach from all players. Read more.


(j) Rise of the Prefabricated Construction
Prefabricated construction is moving to the forefront of the construction industry, because of a worker labor shortage and a need for efficiency. Since modular structures do not allow for modification at the site, they are ideally suited for student housing, education facilities, hospitals and hotels. Read more.


(k) Seattle Rebuilds Seawalls 
The 3,700-ft, $410-million wall is designed to last more than 75 years. It will be as much as 15 ft west of the site of the current wall to accommodate construction design that protects against a 100-year wave event, tsunami waves and surges, while building additional space for habitat. Read more.


(l) Gray Coating to Reduces Heat in Concrete Jungle
Heat can become trapped in urban settings, a phenomenon knows as heat island effect, and Los Angeles and other cities are looking for ways to reduce it. CoolSeal, a gray pavement coating designed to reflect the sun, has shown in a pilot project that it can reduce temperatures by as much as 10 degrees. Read more.

(m) Hurricane Building Codes Work
Homes built to stricter standards fared better in the storm, in Florida. 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) EN 16757:2017
Sustainability of construction works - Environmental product declarations - Product Category Rules for concrete and concrete elements. Read more.

Teaching, Training and Research
(a) Professional Training Course on Durable, High Performance Cement & Concrete with Mineral & Chemical Admixtures
Dr J D Bapat offers professional training course on “Durable, High Performance Cement & Concrete with Mineral & Chemical Admixtures ”. Two-day course is useful for engineers working in cement plants, cement and admixtures marketing, construction sites, higher education. Duration and content: tailor-made as per participants’ requirement. Venue: as per sponsor’s preference. Download brochure. Read more.

(b) Concrete to Help Solve the Problem of Air Pollution
Sulfur dioxide, a major contributor to air pollution, is removed from the air by concrete surfaces, new research shows. Read more.  


(c) Floating Tunnel

Series of experiments from the Norwegian University of Science and Technology’s (NTNU) Centre for Advanced Structural Analysis, or CASA, could pave the way for an entirely new type of water crossing: submerged floating tunnels. Experiments in a shock tube at CASA’s research laboratories show that concrete can tolerate much more pressure than previously thought. Read more.


(d) Concrete Sensors Measure Strength and Humidity
The sensors are tied to reinforcing steel within the concrete slab or formwork which enables wireless and continuous monitoring of concrete temperature and strength using Bluetooth technology to transmit data to a smartphone application. Read more.
