Construction Precast Development

On the one hand, the main purpose of watering and curing concrete is to maintain sufficient moisture on the surface of the concrete structure within the specified time, which is the basis of cement hydration reaction.

On the other hand, only by controlling the external conditions of watering and curing concrete can it be conducive to temperature control and avoid the occurrence of cracks.

In the specific process of concrete watering and curing, operators often have a misunderstanding of the purpose of concrete watering and curing, and only understand it as a prescribed operation, without much value to the concrete structure itself.

Before watering and curing concrete, construction personnel should be organized together to learn the process and principles of concrete watering and curing, clarify the purpose of concrete watering and curing, increase the attention of construction personnel to concrete watering and curing, and guide specific behaviors in concrete watering and curing work, thus achieving the improvement of the quality of concrete watering and curing work.

Memory mnemonic: There are three benefits to pouring through the warehouse: overall improvement of heel stress, economical use of seamless boards, and advanced efficiency improvement for large-scale projects.

Where there is good, there is weakness.

The temperature control requirements are high.

Should the conclusion of the rebound core method for testing the compressive strength of structural solid concrete in the previous text be qualified or meet the design requirements? This article explains how to draw conclusions about the rebound core method for testing the strength of structural solid concrete.

There is a message asking how to draw conclusions when using the rebound method for testing, providing a brief explanation.

At the same time, it supplements the provisions and understanding of the acceptance standards for structural solid strength testing for reference.

.

In existing building safety inspection and appraisal, old community review, and factory reliability assessment projects, the compressive strength of concrete is the core indicator that determines whether the structure can continue to be used, whether it should be reinforced, and whether it can pass the acceptance inspection.

The three most commonly used methods for on-site work are rebound method, core drilling method, and ultrasonic method (ultrasonic rebound comprehensive method).

Lightweight aggregate concrete has broad application prospects in the field of highways due to its lightweight and good seismic performance.

Lightweight aggregate concrete can significantly reduce the self weight of the structure while ensuring its bearing capacity, which meets the development needs of modern green and low-carbon buildings.

However, the performance of lightweight aggregate concrete is significantly affected by the preparation process, especially the porous and water absorbing characteristics of lightweight aggregate itself, which can lead to unstable workability and large mechanical property dispersion of the mixture.

(3) The pouring of the dome concrete construction sections C1-C2 is carried out simultaneously by three pump trucks.

The positions of pump truck 1, pump truck 2, and pump truck 3 are shown in the following figure.

Elephant Foot Ferrule

Following the principle of symmetrical pouring, pouring is carried out in a clockwise direction.

Pump trucks 1, 2, and 3 are moved once during the pouring process, and each pump truck completes the dome pouring within a 120 ° range.

The main causes of cracks: cracks caused by external loads (including static and dynamic loads during construction and use); Cracks caused by deformation (including temperature, humidity deformation, uneven settlement, etc.

); Cracks caused by construction operations such as production, demolding, maintenance, stacking, transportation, lifting, etc.

Classification of cracks: Classified by the direction and shape of cracks, there are horizontal cracks, vertical cracks, transverse cracks, longitudinal cracks, oblique cracks, and radial cracks; According to the depth of cracks, there are three types: through cracks, deep cracks, and surface cracks; Classified by causes, there are mainly plastic cracks, shrinkage cracks, temperature cracks, and uneven settlement cracks.

In March 2026, the Outline of the 15th Five Year Plan for National Economic and Social Development of the People’s Republic of China was officially released.

This landmark document, spanning tens of thousands of words, not only outlines the country’s development blueprint for the next five years, but also lays the “golden track” for the concrete and cement products industry between the lines.

Recently, we have published several articles on concrete tax reform – from the policy warning of “3% tax rate cancellation, 13% era approaching”, to the preliminary suggestion of “how to maintain profits”, to the urgent reminder of “4 things must be done”.

Lifting Socket

Each article has received a lot of comments, but what people are most concerned about is: how to deal with old contracts after the policy has been implemented? How to issue invoices for cross period business? How should various departments within the company cooperate?.

Concrete gradually hardens and increases its compressive strength through the bonding effect of cement.

Due to the fact that the hardening of cement is not achieved overnight, but gradually becomes perfect over time.
