13 sets of typical cases of special construction plans for hazardous projects (3D color images), including Bailey beam high formwork, steel structure, large-span high suspended structure formwork platform, aluminum alloy formwork support, cast-in-place box girder, tower crane installation and removal, corridor suspended ceiling curtain wall hoisting, hydraulic climbing formwork, steel mesh frame, bridge jacking, foundation pit support, earthwork excavation, cantilever scaffolding, cable tower and other special constructions.

They play a key role in eliminating major accident hazards in construction and preventing major safety risks in engineering construction, and are provided for learning and reference.

Concrete used for hydraulic structures such as dams, water gates, pump stations, embankments, bridges, culverts, etc.

is called hydraulic concrete.

The reasonable design of hydraulic concrete and strict control of its construction quality are important guarantees for the engineering quality of hydraulic structures, which are related to the safe operation of the entire hydraulic structure.

Therefore, during the entire process of constructing hydraulic structures, the quality of concrete should be tracked and tested from beginning to end to ensure that the quality of concrete used for hydraulic construction meets design requirements, is stable, and has minimal fluctuations.

Those who study engineering, especially civil engineering related majors, as well as those engaged in civil engineering project design, construction, supervision, and budgeting, inevitably have to deal with the word “tong” frequently.

Speaking of the word ‘concrete’, it’s a bit awkward.

According to the Announcement of the Ministry of Finance and the State Administration of Taxation on the Connection of Value added Tax Preferential Policies after the Implementation of the Value added Tax Law, starting from January 1, 2026, general taxpayers who sell self-produced commodity concrete made of cement as raw material cannot choose to use the simplified tax calculation method for taxation, and can only apply a tax rate of 13%.

The introduction of the new policy has attracted widespread attention in the industry.

The following is a summary of research feedback on some concrete enterprises in Central China.

The particle size of stones directly affects the strength, workability, and compactness of concrete.

Precast Round Ferrule

It is not necessarily better to have larger or smaller stones.

The promotion of recycled aggregate concrete (RAC) is an important way for the construction industry to achieve carbon neutrality and sustainable development, but it has problems such as reduced mechanical properties and insufficient bonding performance with reinforcement, which limits its structural applications.

Plastic Rebar Chairs

Basalt fiber-reinforced polymer (BFRP) reinforcement has become a high-quality alternative material to traditional steel bars due to its corrosion resistance, lightweight, and high strength.

Fiber addition is a common method to improve the performance of recycled aggregate concrete.

Concrete mix design is a core skill essential for technical personnel in concrete enterprises, and it is also a topic that every concrete practitioner needs to delve into.

Whether it is the repeated debugging of front-line technicians or the theoretical research of experts and scholars, ultimately a set of design methods that are suitable for their own production conditions and engineering needs needs needs needs needs to be found.

Various mix design schemes have been proposed both domestically and internationally, each with its own advantages and disadvantages.

However, it is still difficult to find a universally applicable and scientifically unified optimal solution.

Therefore, the core essence of concrete mix design lies in the principle of “there is no fixed method, the key lies in finding the right method”.

The best design is suitable for the production of one’s own enterprise and meets the actual needs of the project.

This also corresponds to the saying “there are a thousand Hamlets in a thousand people’s hearts” – different practitioners can always find different ways of mix design by combining their own experience.

At present, there is no relevant standard or specialized research in China on the calculation method of the effect of adding different amounts of water before the initial setting of ready mixed concrete on the compressive strength of concrete.

Reference materials include the relevant standard JGJ55-2011 “Code for Design of Ordinary Concrete Mix Proportion” and a few literature, but there are certain limitations and irrationality in their use.
