High performance concrete is a type of concrete that significantly improves various performance indicators on the basis of ordinary concrete.

It is made using modern concrete technology such as low water cement ratio, high water reducing polycarboxylate superplasticizer, and large amount of ultra-fine mineral admixture.

Its main technical indicators are excellent durability, high compressive strength, good impermeability, corrosion resistance, frost resistance, and inhibition of concrete alkali aggregate reaction.

Metal Rebar Caps

Its concrete mixture has excellent workability (and ease of use), strong applicability, and is also an economical and environmentally friendly concrete.

The daily work of concrete technicians cannot be separated from communication, just like communication between departments, reporting work to leaders, conducting technical briefings with the construction site, and negotiating control of the construction process.

.

These tasks require laboratory technicians to have good communication and expression skills.

Good communication skills can sometimes achieve twice the result with half the effort, but improper communication can also be detrimental to work and even affect collaboration between departments and external parties.

Improving communication and coordination skills should be a part of the abilities that concrete technicians need to enhance.

In renovation and reinforcement projects, it is common to encounter the situation of adding new floor slabs.

Below are the detailed drawings of the connection between the newly added floor slabs and the newly added cantilever slabs in concrete structures.

The production task order is the original record reflecting the practical production status of the concrete mixing plant.

It is an instruction book that arranges and directs the production of the company, and is the basis for detailed implementation of production effects.

It must be strictly handled according to procedures.

The current cracking risk assessment mainly relies on the coupled simulation technology of temperature field and stress field.

Li Fazhang et al.

used MIDASFEA software to simulate the temperature spatiotemporal distribution of the bottom plate of Xijin Ship Lock under different molding temperatures and layer thicknesses.

Combined with the constrained stress model, they quantified the cracking risk and proved that reducing the molding temperature (better than adjusting the layer thickness) is the key to controlling cracks.

Liu Yi and others proposed intelligent monitoring technology, which constructs a predictive model by collecting real-time temperature data to achieve dynamic warning and regulation.

After comparing traditional models, Tong Liyong and others developed a new prediction model with stable error (<0.

Like other commodities, the performance of concrete is influenced by raw materials.

Steel Chamfer

Only by controlling the quality of concrete raw materials and utilizing them reasonably can we obtain high-performance and low-cost concrete.

The multifunctional platform for tunnel lining concrete curing can simultaneously take into account concrete curing, concrete testing and repair, and cleaning and maintenance of embedded parts.

Plastic Rebar Chairs

The use of its automatic sprinkler system for curing concrete, as well as the use of a platform for inspection and repair of concrete, cleaning and maintenance of embedded parts, has the characteristics of strong applicability, easy operation, high efficiency, good curing effect, high safety, and reduced labor.

Colleagues who have worked on renovation and reinforcement projects should have seen early concrete structure construction drawings, where detailed drawings of each beam were required, resulting in extremely low work efficiency.

Nowadays, concrete structure construction drawings adopt the architectural structure construction drawing plane integral representation method (referred to as “plane method”).

The expression form of plane method is to directly express the dimensions and reinforcement information of structural components in the structural layout plan of various components according to the drawing rules of plane integral representation method, and then combine with standard structural detailed drawings to form a complete set of structural design and construction drawings, which greatly improves work efficiency.
