The manual focuses on common quality issues in civil construction of building engineering, and summarizes key problems such as leakage and cracking.
It uses a visual display of the problems with illustrations and text, analyzes the causes of the problems, and proposes prevention and control measures.

The concrete mix ratio is calculated by a qualified laboratory and determined after trial adjustment.
The concrete mix ratio should be the weight ratio.

Let’s first clarify a core fact: since the implementation of Announcement No.
10 of 2026 by the Ministry of Finance and the State Administration of Taxation, there has been no transition period, no buffer period, and no special subsidies.
General taxpayers in the national concrete industry have completely bid farewell to the 3% simple tax calculation and entered the era of “hard constraints” of 13% general tax calculation.
This is not a policy adjustment, but the beginning of industry reshuffle.
Companies that cannot keep up with the pace will only be gradually eliminated.

Major project construction is the “ballast stone” for stabilizing economic growth, and also the “strong engine” for promoting high-quality economic development, playing a crucial role in the economic development of various regions.
As an important pivot of economic development and a key lever for high-quality development, its strategic value and practical significance are particularly prominent.

In winter construction sites, road surfaces, etc.
, cracks of varying sizes can be seen on the second day after the concrete pouring is completed, and there are more through cracks.
To effectively avoid this problem, attention needs to be paid to multiple aspects:.
Check the wear of the lining plate, blades, and mixing arm, and replace them in a timely manner if they are severely worn; Check the shaft end seal to ensure no leakage of slurry or oil; Perform a jog test run, confirm there are no abnormalities, and then conduct a no-load test run, listening for any abnormal noise or shaking.

Recently, at the construction site of the T1 and T2 sections of the Shiqiao Extra Large Bridge on the Nanraocheng East Yanta City to Jinxian Expressway in Nanchang, machinery roared and personnel were busy.
The crane smoothly lifted the precast concrete slab, and the workers accurately aligned, calibrated, and fixed it.
The entire set of movements was completed in one go, and the construction site was full of enthusiasm.

The era is iterating forward, and the wave of architectural industrialization is sweeping across the globe.
When modern architecture is situated in the hinterland of national cultural heritage, finding a balance between historical preservation and design innovation has become a common proposition in the global architecture industry.
