Analysis and Prevention of Horizontal Random Cracks in Cement Concrete Pavement
At present, China’s cement production accounts for about 50% of the world’s total output, and has maintained the world’s top position for 21 consecutive years.
Based on the advantages of domestic cement resources, cement concrete pavement is widely used and has played a huge role in the national economic construction and sustainable development.
During use, it has also been found that a considerable portion of the road surface has structural defects such as cracking, breakage, subsidence, and misalignment to varying degrees, especially transverse cracks (regular and irregular), which not only pose great difficulties for maintenance and repair, but also seriously affect the functionality and service life of the road surface, becoming a technical difficulty that restricts the development of cement concrete pavement.
This article focuses on the analysis of the hazards, causes, and prevention measures of transverse random cracks in cement concrete pavement based on the actual reconstruction project of the Yueqing Mountain Old Connection Highway, in order to provide benefits for future road construction.

Literature Sharing 108: Testing and Analysis Evaluation of Rubber Crushed Concrete with Composite Industrial Waste Aggregates and Auxiliary
Under the trend of green and sustainable development in the concrete industry, the use of industrial waste and waste tires to prepare rubber crushed concrete has become a research hotspot.
However, the addition of rubber often leads to a decrease in the mechanical strength of concrete, limiting its engineering applications.
A recent study published in Construction and Building Materials successfully solved this pain point by blending various industrial waste aggregates and mineral admixtures.
It not only greatly improved the strength and durability of rubber crushed concrete, but also constructed a machine learning model to achieve accurate prediction of its strength, providing a new idea for the research and application of green concrete.

Analysis of the impact of various factors on concrete tax rates ranging from 3% to 13%
In 2026, a seemingly ordinary No.
10 document from the Ministry of Finance triggered a profound interest shock in the construction industry chain.
The document stipulates that from January 1, 2026, the concrete tax rate will be adjusted from 3% to 13%.
The 10% tax rate difference, like a butterfly flapping its wings, has sparked a game between the first party, construction party, and supplier regarding the logic of value-added tax, contract risks, and survival space.

Talking about the tax reform of the concrete industry in 2026, we must clarify these issues!
On January 1, 2026, with the official implementation of Announcement No.
10 of 2026 by the Ministry of Finance and the State Administration of Taxation, the commercial concrete industry ushered in the most drastic tax reform in nearly a decade.
The 3% simple taxation policy, which used to be a reassurance for the industry, has been completely abolished and replaced by a 13% general taxation model.
This change is not only an adjustment of tax rate figures, but also a watershed for the entire industry to transition from extensive operation to compliance management.
How to deal with old contracts? How to issue invoices for cross period business? How should various departments within the company cooperate? These have become issues that we must clarify.
