1.Raw materials The fineness modulus and silt content of sand must meet the requirements, and the water content should not exceed 6% during use. The sampling of sand must not take the surface layer and the oversize particles of the upper gravel, etc. must meet the requirements, especially the silt content (stone powder content). If … Continue reading
In the field of construction engineering, concrete is a widely used building material, and its performance is directly related to the safety and durability of the entire building structure. However, in cold regions or during winter construction, concrete frost damage often occurs, causing many problems in construction. A deeper understanding of the causes of concrete … Continue reading
Imagine if we could build new buildings using renewable concrete bricks. Although it may not be immediately obvious, the construction industry is actually one of the major sources of greenhouse gas emissions, which are gradually causing global temperatures to rise. However, a new technology that will be publicly available for the first time in 2021 … Continue reading
In the construction industry, concrete is widely used in various engineering structures and plays a pivotal role. The stability of its performance and the reliability of the construction quality are directly related to the safety performance and service life of the building. However, during the actual construction process, a headache problem often occurs, that is, … Continue reading
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have pioneered a 3D concrete printing method that captures and stores carbon dioxide, marking a major step toward reducing the construction industry’s environmental footprint. The innovative technique offers a promising solution to mitigate cement’s massive carbon emissions. The process works by integrating CO₂ and steam—byproducts of industrial … Continue reading
High-performance concrete is concrete with excellent workability, mechanical properties and durability that is made to meet the specific requirements of construction projects using high-quality conventional raw materials and an optimised mix design, through green production methods and strict construction measures. As an important green building material, the promotion and application of high-performance concrete in infrastructure … Continue reading
A private-public partnership has paved a section of Minnesota road with an experimental low-carbon concrete mixture that resulted in greater strength and lesser cement use, saving money and carbon. Concrete and its most important ingredient, cement, is one of the most carbon-intensive industries on Earth because it’s used so often in construction. It has virtually … Continue reading
The world’s first,S$200 million ready-mixed concrete ecosystem has officially opened at Jurong Port. Its productivity will double, and it will reduce carbon emissions by more than 25,000 tons per year, equivalent to the annual electricity consumption of about 12,750 four-room HDB flats. Ready-mixed concrete is one of the most commonly used materials in construction. It is … Continue reading
The Conit Runner robot has been nominated for a CES 2025 innovation award When most of us think of freshly poured concrete, we picture a material that should be left to dry as smooth as possible. A new wheeled robot drives right over the stuff, however, gouging its surface to make structures stronger yet also … Continue reading
ANTI CRACK FIBER Anti crack fiber is a new type of fiber of concrete and mortar which is composed of polypropylene and polyester. It is called secondary reinforcement of concrete. With the development of composite materials, anti crack fiber has been widely used in civil engineering. The results show that when the crack resistant fiber … Continue reading
