Why is the thickness of the cover a key factor in concrete construction? Today, let’s try to analyze its technical principles and construction essentials, as well as common construction measures and knowledge of common problems and their prevention. I. Technical principles Reinforcing steel corrosion prevention The highly alkaline environment of concrete (pH ≥ 12.5) forms a.. read more →
Apart from improving the quality of the concrete raw materials and construction techniques, if the strength is found to be insufficient after production, what emergency treatment methods can be used? We will explain them one by one below… 1. Changing external forces There are four ways to reinforce concrete with insufficient strength: direct reinforcement, increasing.. read more →
Steel slag can be used to reduce carbon emissions in the concrete and cement industry, but the amount available in the future is gradually decreasing as the steel industry implements various measures to reduce its carbon footprint. The main source of carbon dioxide emissions is the built environment. Steel, concrete and cement are all important players in.. read more →
01Understanding the consistency and workability of concrete mixtures Workability is a crucial and mysterious concept in the field of concrete construction. It is not just a simple term, but a comprehensive reflection of the multidimensional properties of concrete mixtures during construction operations. So, what exactly is the workability of concrete mixtures? What are the key.. read more →
The appearance of concrete is a visual representation of its quality. The evenness and luster of the concrete surface is of increasing concern to construction contractors and property owners, and their requirements are becoming more and more stringent. This has gradually become an important economic factor. Bleaching is the most common phenomenon on concrete surfaces… read more →
Specific limitations Over the past few decades, concrete has become the main material in construction, especially in densely populated urban environments. Thanks to its low cost, ease of use and scalability, concrete has gradually replaced bricks, stone and wood. But it is not without problems. Sustainability First and foremost, it is far from a sustainable.. read more →
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.. read more →
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.. read more →
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.. read more →
