In order to implement the market-oriented reform of engineering cost, strengthen the dynamic management of pricing basis, and provide supporting support for the implementation of the “Valuation Standards for Construction Engineering Quantity List” GB/T 50500-2024 and various professional engineering quantity calculation standards, the Provincial Department of Housing and Urban Rural Development has revised and adjusted a series of construction engineering cost pricing basis such as “Composition and Calculation Rules for Construction Engineering Cost Projects in Shandong Province”, “Consumption Quota for Construction Engineering in Shandong Province”, “Consumption Quota for Installation Engineering in Shandong Province”, “Consumption Quota for Municipal Engineering in Shandong Province” and “Consumption Quota for Landscape and Greening Engineering in Shandong Province”, which will be implemented from November 1, 2025.

Cracks are the most common early disease of cement concrete pavement and the core starting point for inducing structural damage.

From the perspective of engineering operation and maintenance, pavement cracks can be mainly divided into two categories: one is load type cracks, which are generated by repeated impacts and long-term fatigue effects of vehicle wheel loads, and often develop synchronously with slab bottom detachment and stress concentration; The other type is non load type cracks, which are dominated by the volume deformation of concrete, and the core causes are temperature shrinkage and drying shrinkage.

Chemical shrinkage accounts for a very low proportion and is generally not the main controlling factor.

10 of 2026 by the Ministry of Finance and the State Administration of Taxation, starting from January 1, 2026, the original 3% simplified tax calculation policy for general taxpayers of commercial concrete will be officially abolished, and the 13% value-added tax rate will be uniformly implemented for self-produced ready mixed concrete.

Up to now, it has been implemented for about half a year, changing the tax calculation and deduction rules for concrete materials in the construction industry, which has had a significant impact on the entire construction chain, including concrete mixing plants, construction general contractors, construction units, and cost audits.

Fabric reinforced concrete (TRC) is widely used in the reinforcement of thin-walled components and structures due to its lightweight, corrosion resistance, and excellent crack control properties.

In the context of sustainable building development, natural fiber fabrics such as flax have attracted attention as low-carbon alternative materials.

However, under unified experimental conditions, there is still a lack of direct comparative research on the mechanical properties of flax with traditional carbon fiber and alkali resistant glass fiber TRC.

: Mineralized carbonates endow ancient Roman concrete with millennium durability.

The intuitive manifestation of concrete compaction is that when the vibrating rod is pulled out, there is floating slurry on the surface of the concrete, and it no longer sinks significantly.

During the vibration process, excessive vibration should be avoided to prevent segregation, and insufficient vibration should not cause honeycomb and rough surfaces.

The insertion vibrator should be inserted quickly and pulled slowly, with evenly arranged insertion points and a movement distance not exceeding 1.

Many villagers always focus on the layout and exterior wall decoration when building houses, ignoring that the foundation is the foundation of the entire house.

Cutting corners in foundation construction and selecting the wrong foundation type can lead to wall cracking and ground settlement after three to five years of occupancy, resulting in extremely high maintenance costs in the later stages.

I have previously written two informative articles, “Complete Approval Process for Building Houses on Rural Homesteads in 2026, One Step at a Time, Avoiding Illegal Buildings and Demolition!” and “Guidelines for Site Selection and Pit Avoidance of Rural Homesteads.

” For those who are unsure about the approval of homesteads and how to choose land parcels, they can take a look first.

Today, specifically for self built houses in plain areas, I will explain the four mainstream foundations, reinforcement standards, concrete grades, excavation of foundation pits, soft soil treatment, demolition of old buildings and construction of new ones, and neighborhood foundation protection, all in accordance with the current regulations for rural house construction, without exaggeration.

In order to help scientific researchers and engineers in the fields of materials, civil engineering, geotechnical engineering, machinery and high-end equipment, and systematically master the cutting-edge methods of AI enabled materials and structures, we collated and launched the essence of high-quality thematic training sponsored by Beijing SoftResearch International Information Technology Research Institute and hosted by Interact (Beijing) Education Technology Co.

, Ltd.

, covering the three cutting-edge directions of AI enabled composite material mechanics, machine learning in the application and practice of intelligent cement-based composites, and geotechnical engineering PINN practice.

Whether you are a master’s or doctoral student engaged in advanced composite materials, intelligent cement-based, geotechnical mechanics research, a university scholar, or a research and development engineer dedicated to the intersection of AI+materials/civil engineering/geotechnical engineering, you can build a complete technical system through systematic practical courses, quickly implement research projects, reproduce top journal achievements, and break through engineering bottlenecks.

The specific relevant matters are notified as follows:.

The loss of concrete slump refers to the gradual decrease in the flowability of freshly mixed concrete over time, which is an inevitable phenomenon in the process of concrete hydration and hardening.

The core reasons for this phenomenon can be mainly divided into seven categories, which are briefly explained as follows:.
