Cement Manufacturing

(a) Hima Cement, Uganda, Fuels with Waste

Geocycle will provide provide waste as fuel for the LafargeHolcim-owned Hima Cement in Uganda. Read more. 

(b) Resin for Dust Suppression

Field testing of PennzSuppress D shows the product to be highly effective for controlling dust from unpaved roads. the resin is environmentally friendly. Read more.

(c) Heidelberg Cement Researches CO2 Binding

aThe natural minerals olivine and basalt are able to bind CO2 over their entire life-cycle. With natural absorption, it takes decades until the minerals are saturated with the greenhouse gas. The research project intends to speed up the absorption process. If successful, carbonised minerals can be used for various product applications. Read more. 

Concrete, Mineral and Chemical Admixtures

(a) X-Ray-Style Technology Detects Early Corrosion in Concrete

Researchers at the National Institute of Standards and Technology have figured out how to detect deterioration inside infrastructure. Their system can pinpoint corrosion in the rebar inside concrete before it becomes a problem. Read more.

(b) Wind-Resistant Concrete Power Pole

Florida Power & Light installed a new concrete power pole in St. Augustine, as part of an ongoing effort to make the energy grid more reliable and storm resilient. Read more.

(c) Massive Precast Concrete Girders Installed at Bridge Project

137-ft. Super Girders Used to Replace Washington’s Miles Creston Bridge. Read more.

(d) Concrete Column Creates Energy from Waves

The device is developed by Australia's Wave Swell Energy. It comes in the form of a concrete column in which waves flow in and out of a central chamber, creating an oscillating water column, to move turbine. Read more.

(e) Concrete Floating Dry Dock

Designed for durability of 200 years, the newest dry dock in the market has recorded an engineering breakthrough in the adoption of high quality concrete for marine construction. Floating concrete structures are far more durable and economical if lifetime cost analysis is considered. Read more.

(f) Concrete that Resists Road Salt Deterioration

Calcium hydroxide in concrete can mix with deicing salt and cause deterioration. To combat this problem, a researcher at Drexel University's College of Engineering has developed a concrete mixture that combines fly ash, slag and silica fume, and is more resistant to the chemical reactions from road salt.  Read more.

(g) Novel technology applied to replace aging bridge

The old bridge was replaced with what is known as a geo-synthetic reinforced soil integrated bridge system (GRS-IBS). Developed and promoted by engineers at the Federal Highway Administration, this system lends itself to rapid and cost-effective construction. Read more.

(h) Recycled Tires Create Stronger Concrete

Engineers have developed a more resilient type of concrete using recycled tires that could be used for concrete structures like buildings, roads, dams and bridges while reducing landfill waste. Read more.

(i) Cladding in London Tower Fire Banned for Tall Buildings in US

The cladding on the London tower that burned this week is banned in the US for buildings taller than 40 feet, because of the fire and smoke spread. A fire-resistant form of the aluminum panels could have been used, with little extra cost. Read more.

(j) Novel technology to Replace Aging Bridge

The old bridge was replaced with what is known as a geosynthetic reinforced soil integrated bridge system (GRS-IBS). Developed and promoted by engineers at the Federal Highway Administration, this system lends itself to rapid and cost-effective construction. 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.

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) Design Strength Requirements for Externally Applied Reinforcing Systems

This free online education presentation covers external reinforcing systems; requirements of ACI 562-16 Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary; effects of fire on concrete; and fire protection. Read more. 

(c) Better Way to Calculate Indoor CO₂

Measurements of indoor carbon dioxide (CO₂) concentrations are used to evaluate indoor air quality. Read more.  

(d) Polymer Wrap to Renew Deteriorating Concrete

The researcher at West Virginia University believes deteriorating roads and bridges should not be replaced, but rather renewed, with a polymer-based product that already has been used on two bridge projects in the Northern Panhandle. Read more.

(e) River Alternative to Border Wall

Massachusetts civil engineer Frank K. Johnson has proposed building a monolithic enclosed concrete-and-steel culvert along the border between the US and Mexico from California to the Texas Gulf Coast. The idea is create a border river of sorts to transport seawater that would generate electricity for some areas and be desalinated for use in desert areas. Read more.

(f) Bio-Receptive Concrete

Researchers at University College London's Bartlett School of Architecture have created a magnesium phosphate-based concrete that allows organic material to grow on the surface without soil or irrigation. Growing plants on the concrete could help increase green spaces in urban environments. Read more.
