New regulations from the Housing and Urban Rural Development Bureau! It is strictly prohibited to step on steel bars directly during

After the completion of the binding and installation process of the floor reinforcement, it is common to encounter situations on site where management personnel carry out inspection and acceptance work, and construction personnel frequently walk and directly step on the reinforcement during concrete pouring operations.

This behavior can easily cause the displacement of steel bars or cushion blocks, leading to quality problems such as excessive deviation in the thickness of the steel bar protective layer.

GB/T50784-2013 Basic principle of ultrasonic method for measuring internal defects in concrete. When there are defects inside the concrete

The defect free area in concrete allows sound waves to propagate in a straight line with the shortest distance traveled; When encountering defects such as holes, cracks, and loose layers, sound waves cannot directly pass through (defects are mostly gas/liquid media, with a large difference in acoustic impedance from concrete, which can cause reflection and refraction), and can only pass through the intact concrete around the defect, with the actual propagation path far greater than the geometric distance measured.

Discussion on Antifreeze Concrete and Antifreeze Concrete

In the construction industry, some construction workers often refer to winter construction concrete and concrete with frost resistance requirements in structural design as “frost resistant concrete”.

The author believes that the concrete used in winter construction mainly adopts technical measures to prevent frost heave damage before reaching the critical strength after pouring, which meets the technical requirements and should be called antifreeze concrete.

The structural design has requirements for frost resistance grade, and only concrete with long-term resistance to freeze-thaw cycles should be called frost resistant concrete.

It’s getting cold, a winter construction reminder for the workers of the concrete construction unit

In the spirit of being responsible for engineering quality, our company has put forward higher requirements for concrete production in this stage and developed a comprehensive winter construction technology plan: during the winter concrete construction process, our company uses antifreeze and water reducing agents, reduces water cement ratio and other methods to prepare concrete, and increases efforts in raw materials, production process, quality control and other processes to ensure that the quality risks of concrete production, transportation, pouring and other links are minimized.

While our company takes technical measures for winter construction of concrete, the pouring, curing, and maintenance of concrete will also have a direct impact on the quality of concrete structures.

In order to prevent quality accidents to the greatest extent possible, the relevant matters are introduced below in order to achieve good results and help you create excellent projects.
