In order to further promote the integrity construction of the concrete and cement products industry, standardize the industry credit order, and enhance the awareness of enterprise integrity, our association has carried out industry credit evaluation work for 14 consecutive years.

According to the spirit of the State Council’s “Outline of the Plan for the Construction of the Social Credit System (2014-2020)” (Guofa [2014] No.

21), the State Council General Office’s “Guiding Opinions on Accelerating the Construction of a New Credit based Regulatory Mechanism for the Construction of the Social Credit System” (Guobanfa [2019] No.

35), and the “Comprehensive Supervision Measures for Industry Associations and Chambers of Commerce” (NDRC [2016] No.

2657) issued by 10 departments including the National Development and Reform Commission, our association will continue to carry out credit evaluation work in the concrete and cement products industry in 2026 in accordance with the relevant provisions of the “Management Measures for Credit Evaluation in the Chinese Concrete and Cement Products Industry”, following the principles of “openness, fairness, and science”.

The relevant matters are hereby notified as follows:.

The Xi’an Housing and Urban Rural Development Bureau has issued a notice to strictly regulate the production and construction quality management of ready mixed concrete in response to the recent discovery of substandard concrete strength during provincial inspections.

Strictly review the qualifications of production enterprises, implement on-site joint acceptance, strictly prohibit unauthorized addition of water and making test blocks on behalf of others, and hold the five parties responsible for construction, supervision, testing, and production enterprises accountable.

Those who fail to meet the strength standards and falsify data shall be ordered to stop work for rectification and held accountable.

A good ratio is both “tested” and “waited” for.

Cement, slag, fly ash, water cement ratio, aggregate gradation – with multiple variables, the combination space can explode directly.

By relying on orthogonal experiments to achieve a 28 day strength from mixing to extrusion, a set of ratios has a long cycle, high cost, and consumes both manpower and time.

Traditional empirical formulas find it difficult to fully understand the thick nonlinear relationship between components and strength.

If the prediction is biased, the engineering risk will be amplified accordingly.

You can integrate others, which means you have the ability to be integrated by others, which means you have value.

No one works with anyone, it is a cooperative relationship that achieves mutual success and mutual benevolence, which can create new miracles.

The World of Concrete Asia, as the Asian station of the “Concrete World Expo” series of well-known exhibition brands in the global concrete industry, showcases high-quality products and leading technologies in the three major fields of concrete, flooring, and mortar in one stop.

The exhibition focuses on the construction of concrete floors and develops towards concrete facade buildings, including concrete building raw materials, concrete building additives, concrete building and mechanical equipment, concrete surface treatment equipment and accessories, flooring raw materials, diverse flooring systems, finished mortar, mortar additives, complete sets of mortar production and spraying equipment, and other products.

WOCA has been built into a one-stop exhibition and trading platform for the concrete, flooring, and mortar industries, promoting the green, international, and diversified development of the concrete construction industry in Asia.

Brick concrete structure: Brick walls bear vertical loads.

Shuttering Magnet

Brick concrete structure refers to the use of bricks or blocks to build the walls of vertical load-bearing structures in buildings, and reinforced concrete structures to construct columns, beams, floor slabs, roof panels, and other horizontal load-bearing structures.

The steel-concrete composite structure combines the advantages of steel tensile strength and concrete compressive strength, and is widely used in high-rise buildings and bridge engineering.

The global annual production of construction solid waste is enormous, and resource utilization is the key to achieving sustainable development.

Replacing some of the aggregates in the core concrete of steel tube concrete with building solid waste concrete blocks is a new way to achieve high-value utilization of solid waste.

However, the influence of different replacement rates of solid waste concrete blocks and combinations of steel pipe diameter to thickness ratios on the axial compression performance of components is not yet clear, and the applicability of design specifications also needs to be verified.

Building energy consumption is one of the main sources of global energy consumption, and improving building energy efficiency is crucial for achieving sustainable development.

Spread Anchor

Phase change materials (PCM) can effectively regulate indoor temperature and reduce energy consumption in buildings by absorbing and releasing latent heat during the phase change process.

However, there is a risk of leakage when traditional PCM is directly added to concrete, and shape stabilization needs to be achieved through supporting materials.

Silica fume (SF) and rice husk ash (RHA), as industrial/agricultural wastes, can both stabilize PCM and serve as auxiliary cementing materials, but their effects on PCM stability and thermal performance in foam concrete are still unclear.

In this study, a shape stabilized PCM insulation board based on foam concrete was developed, and its mechanical properties and thermal performance were systematically tested.
