Study on correlation between hydration characteristics and macroscopic properties of ferroaluminate cement system based on isothermal conduction calorimetry
ZHOU Lijuan, et al
The hydration heat release and hydration characteristics of a ferroaluminate cement system were investigated using isothermal conduction calorimetry, with a focus on the correlation between its hydration behavior and macroscopic properties. The results indicate that in a ferroaluminate cement system blended solely with limestone, increasing the limestone content prolonged the initial and final setting times, while the compressive strength at various curing ages and the 7-day cumulative heat release exhibited a declining trend. In a system incorporating both limestone and slag, increasing the slag content caused the setting time to first extend, then shorten, and subsequently extend again. Meanwhile, the compressive strength and 7-day cumulative heat release initially decreased, followed by an increase, and ultimately decreased. A linear positive correlation was observed between the compressive strength of the ferroaluminate cement system and its cumulative hydration heat release at corresponding curing ages. Conversely, a linear negative correlation existed between the setting time and the 7-day cumulative hydration heat release.

Study on optimal control strategy of air volume in kiln system with high coal replacement rate
Hot!
YU Gang, et al.
The large-scale application of alternative fuels in cement production to save energy and reduce carbon emissions has led to increased fluctuations of carbon monoxide concentrations in kiln systems, and excessive air supply has increased energy consumption.Based on the thermal balance analysis and practical test data, this paper systematically proposes an optimal control method for the induced draft fan that allow moderately incomplete combustion in the environment of high substitution ratio of coal.The implementation results proved that this strategy effectively improved the energy efficiency of the plant by optimizing the carbon monoxide and oxygen levels with the control system and refining the air supply.

Optimization of concrete mix proportion based on convolutional neural network prediction model
LI Jianhua, et al.
Based on the performance test datum of the second graded foundation concrete of the Minjiang Laomukong navigation and hydropower junction project, a hybrid neural network based on convolutional neural network and bidirectional long short-term memory network was established, and attention mechanism was introduced to obtain a model that predicts performance through mix proportion. Subsequently, non-dominated sorting genetic algorithm II(NSGA-II) was used to optimize the parameters of the prediction model, which reduced the prediction error of 28 day compressive strength from 38.54% before optimization to 0.26%, and reduced the prediction error of slump from 0.9% before optimization to 0.23%. Then, based on the optimized prediction model, the mix proportion of concrete was optimized using the NSGA-II algorithm with the maximum 28 day compressive strength and slump of concrete as the optimization objectives. The optimized 28 day compressive strength increased by 13.6% compared with the maximum value obtained from the experiment, and the slump also met the engineering requirements. Finally, experimental verification was conducted on the optimal mix proportion, and the results showed that the error between the theoretical 28 day compressive strength and the actual value of the optimal mix proportion was 2.57%, and the error of slump between the predicted value and the actual value was 0.79%, proving that the method proposed in this paper had good optimization effect

Study on influence of aggregate grade on J-ring performance of of self-compacting high-strength concrete
XU Ying, et al.
To prepare self-compacting high-strength concrete, the influence of coarse aggregate gradation ratio of (5~10 mm) and (10~20 mm) crushed stone mass ratio on the J-ring performance of self-compacting concrete was studied. The results indicate that increasing the proportion of large stones within a certain range is beneficial for increasing the concrete flow rate and reducing the expansion time. When the mass ratio of crushed stones is 6:4, the J ring has the smallest barrier extended time. Increasing the proportion of large stones within a certain range is beneficial for increasing the extended degree. When the mass ratio of crushed stones is 6:4, the J-ring blocks the maximum extended degree, but the concrete produces some separation. Increasing the number of large stones within a certain range is beneficial for the self-forming of concrete, but when the number of large stones exceeds a certain limit, it is detrimental to the self-forming of concrete. The suitable ratio of coarse aggregate in this experiment is 8:2.

Research progress on water resistance of magnesium phosphate cement: from hydration mechanism to modification method
QI Haoyu, et al.
Magnesium phosphate cement (MPC) is a novel cementitious material, with the characteristics of early strength, fast hardness, high early strength, good bonding capacity and construction at 0 ℃. Therefore, it exhibits promising potential for applications such as rapid repairs and specialized cementing. However, the poor water resistance of MPC hinders its widespread adoption in numerous fields. This paper provides a comprehensive review of recent advancements in MPC water resistance research, including its hydration mechanism, the underlying causes of its inferior water resistance and various modification strategies. Furthermore, it explores future research directions in this field.

Study on effect of machine-made sand on performance of C50 pipe concrete
WANG Lifeng
Through experiments on the rheological characteristics, mechanical properties, and durability of concrete with 50% and 100% replacement of natural sand by machine-made sand, this study explores the impact of machine-made sand on the performance of pipe concrete. The research shows that the addition of machine-made sand increases the yield stress of the concrete and reduces its plastic viscosity. The compressive strength, splitting tensile strength, and chloride ion penetration resistance of the concrete have significantly improved with the increase of the amount of machine-made sand. Furthermore, a linear relationship is observed between dynamic elastic modulus and compressive strength, splitting tensile strength and electric flux. This indicates that dynamic elastic modulus can serve as a non-destructive testing indicator, providing a reference for the evaluation of compressive strength, splitting tensile strength and electric flux. The findings of this study can offer valuable insights for the application of machine-made sand in pipe concrete.

Optimization of preparation process and performance study of recycled aggregate from gold tailings
CHANG Zhiyang, et al
In view of the problems such as high cost, low utilization rate and limited consumption for the treatment of gold tailings, this paper prepared gold tailings-based recycled aggregates by a turntable ball-forming technology using gold tailings as a raw material. The effects of binder-sand ratio and curing methods on the properties of gold tailings recycled aggregate were investigated, such as particle size, water absorption rate and crushing value. The results showed that water absorption rate and crushing value of recycled aggregate decreased with the increase of the binder-sand ratio. Compared with steam curing and standard curing, carbonization curing reduced the water absorption and crushing value of regenerated aggregate. The optimal composition of gold tailings-based recycled aggregate is 50% cementitious materials and 50% gold tailings. The optimal recycled aggregate had an apparent density of 2 650 kg/m3, water absorption rate of 3.2% and crushing value of 3.1%. The 28 d compressive strength of concrete prepared with 10% recycled aggregate was 52.5 MPa, slightly lower than that of control concrete, which was in line with the standard requirements
