1. Ready-mixed concrete
Ready-mixed (commercial) concrete It has been used for a relatively short time in the development process of our country. Due to the relative lack of experience in use, this has caused the relevant personnel to still have great flaws in the application explanation during the use process. On-site Under the influence of mixing ideas, some on-site construction workers still stick to the traditional concept of on-site mixing during the construction process. In the process of curing ready-mixed (commercial) concrete, they are largely unable to achieve effective results. To maintain the concrete on the ground, this article mainly conducts a corresponding analysis of the construction application technology on the specific problems of the current construction, so as to better ensure the quality of the construction unit during the project construction process, and thus better promote the development of society. Progressive development.
2. Use of anti-segregation agent for ready-mixed concrete
In order to better ensure the quality of concrete, it is necessary for relevant personnel to be familiar with concrete related matters before purchasing concrete. The basis for disclosure, and when making a reservation for concrete, the specific use time of the concrete must be explained. The quantity, strength grade, and pouring location must be clearly explained to the supplier. In short, the relevant requirements must be refined when making a reservation. Only in this way can we ensure that the concrete produced by the concrete company meets the corresponding construction standards. For this reason, it is necessary to make corresponding preparations before making a purchase.
First, strengthen the inspection of pouring conditions. In order to better ensure the quality and safety of construction, the construction unit must effectively inspect the concrete pouring conditions before supplying concrete, and the construction process must be Check the influencing factors of concrete pouring to ensure the smooth progress of pouring during the construction process. The firmness of the formwork support must be effectively checked to better prevent the expansion of the formwork from causing adverse effects during the pouring process. Only after the pouring acceptance has been carried out can the corresponding pouring construction be carried out.
Second, strengthen the supply of equipment at the construction site. For ready-mixed (commercial) concrete, in order to better ensure the quality of the project in related pouring projects, the construction unit must reasonably arrange the construction site and improve the corresponding construction environment. Ensure the smooth flow of roads during the construction process, and provide water, electricity, shunting yards, lighting, etc. to better promote construction. In addition, the relevant procedures that need to be completed by the supplier should also be completed and signed. Issues such as safety damage and loss that occur during the storage of relevant equipment and equipment by the construction unit must be dealt with accordingly according to the signed contract. compensation.
3. Concrete Pouring
The process of pouring concrete includes a variety of processes. In order to better ensure the quality of pouring, it is necessary to effectively carry out each process. Management, the following is some specific analysis.
First, moisturize the pipes. During the concrete pouring work, the construction unit must take appropriate measures to discharge the water and mortar before pumping the concrete. In this regard, the construction unit must discharge the water and mortar outside the mold to better To prevent the occurrence of broken strips, in order to better ensure that the lubrication pump mortar can effectively lubricate the pipeline, the lubrication pump mortar can be dispersed in the mold by spreading the mold.
Second, confirm the concrete grade. When commercial concrete enters the construction site, the type of concrete and the relevant requirements of the construction unit must be reviewed. Only after the relevant information has been accurately confirmed can the concrete be used.The soil is transported to the construction site.
Third, strengthen the management of slump. When arranging the concrete pouring work, the construction unit must do a good job in implementing the specific work. For the testing and acceptance of concrete, special personnel must be assigned to implement the relevant work. When the slump situation is serious, the construction unit must contact the concrete company Make contact, and then personnel will make corresponding adjustments to prevent non-personnel from handling them at will.
Fourth, strictly control the concrete residence time. Since the length of time the concrete stays at the construction site has a direct impact on the slump of the concrete, and has a certain impact on the pumping of concrete to a large extent, for this reason, the effective residence time needs to be determined based on the temperature of the concrete. control.
Fifth, improve the discharge of irrigation water. In order to prevent the impact of the concrete residue in the transport tanker on the environment, the construction unit needs to flush the tanker after pouring, and the flushing location and the discharge of mud water must take into consideration the corresponding environmental issues. formulation of measures.
Sixth, pay close attention to the implementation of concrete pouring technology. First of all, it is necessary to ensure the orderliness of the pouring sequence of concrete. In this regard, during the process of pouring concrete, the pouring of concrete with higher strength should be considered first. During the cross-pouring of concrete, the order of pouring must be clarified and the pouring must be carried out in strict accordance with the corresponding order. During the pouring process, the type of concrete at the pump port must be tested to better ensure the effectiveness of the pouring process. sex.
Secondly, when carrying out concrete vibrating work, the corresponding construction actions must be carried out strictly in accordance with the operating procedures, and the vibrating work must be carried out according to the specific process requirements to avoid leakage of vibration during the vibrating process. When vibrating concrete, it is necessary to prevent the impact of over-vibration on the quality of concrete pouring.
Furthermore, for some concrete with higher fluidity, in order to prevent cracks, the poured concrete must be pressed half an hour after the initial vibration. For some concrete with higher strength, And for concrete that was poured earlier, cracking measures must be taken after pouring to protect the quality of the concrete accordingly.
4. Concrete maintenance work
First, strengthen the maintenance of cast-in-place concrete slabs. Strengthening the maintenance of cast-in-place concrete slabs requires the use of some current new processes to implement specific maintenance work, that is, using the process of rubbing flat sheets and covering them with plastic films to perform corresponding vibration work. In the process of implementing this process, It is necessary to ensure that the plastic film will not be lifted entirely during the laying-out process, so that the corresponding maintenance work can be better carried out.
Second, strengthen the maintenance of concrete columns. The maintenance of concrete columns is mainly to prevent cracks and other problems after the formwork is removed. For this reason, corresponding maintenance of the corresponding concrete columns is required. As a measure, you can wrap the column with plastic film to better prevent the evaporation of moisture inside the column.
Third, strengthen the maintenance of concrete shear walls. In order to effectively maintain the shear wall, a certain amount of curing fluid must be painted on the surface of the shear wall after the formwork is removed. During the painting process, the effectiveness of the painting must be ensured to avoid failure due to insufficient painting. in place and cause a certain degree of water seepage. In addition, it can also be maintained by regularly sprinkling water, but this maintenance cycle is usually more than 7 days, and the best time is to control it within 14 days.
In addition, in addition to carrying out corresponding maintenance measures for concrete, the implementation of work related to concrete form removal should also be strengthened. First of all, the strength of concrete must be effectively tested to ensure that the strength level of the concrete meets the corresponding construction requirements when the formwork is removed, and the corresponding formwork strength must be removed according to the corresponding construction standards. In addition, the formwork removal work should also be carried out. The formwork time should be effectively controlled to prevent premature removal of formwork, so as to better ensure the quality and safety of concrete projects.
