The construction project of Songshan Lake Hospital affiliated to Guangdong Medical College started on September 3, 2018 and completed its main structure topping out on September 30, 2020.

It was fully completed and accepted on January 12, 2021.

The main project of the hospital includes a basement and 15 floors, with a total construction area of 420000 square meters.

In the construction of the basement and standard floor beams and slabs, a large amount of concrete materials are used.

In order to ensure the final construction quality and pouring effect, appropriate testing methods must be adopted in accordance with the corresponding testing specifications to comprehensively test the various indicators and properties of coarse aggregates in the concrete, ensuring that they will not have adverse effects on the performance of the concrete.

Concrete mortar is an important material in construction engineering, and its quality directly affects the stability, durability, and service life of building structures.

Swift Lift Clutches

At present, common mortar quality problems in engineering, such as cracking, peeling, and insufficient strength, have a negative impact on construction efficiency and structural reliability.

Although scholars at home and abroad have conducted relevant research on materials, construction, and management, there is a lack of systematic analysis of actual on-site problems, which urgently needs improvement.

Therefore, this article combines research and experiments to deeply explore the causes of mortar quality problems from the aspects of material selection, mix design, construction technology, and maintenance measures.

Scientific and efficient solutions are proposed to provide reference for improving mortar performance and optimizing industry technology, and to promote the sustainable development of the construction industry.

: Natural carbonation of concrete: data-driven analysis.

During the molding process of concrete, various factors such as materials, processes, and environmental conditions often lead to the formation of bubbles on the surface of the concrete.

A small amount of bubbles will not have a significant impact on components or buildings, but too many bubbles will bring a series of problems.

(When the air content of concrete increases by 1%, the compressive strength at 28 days decreases by 5%.
