aggregate gradation
发音：/??gr?d???ɡe??n/
英语范文：
The aggregate gradation of a riverbed determines its stability and capacity to absorb water.
河流底部的聚集分级决定了它的稳定性和吸收水的能力。
英语作文音标和基础释义：
aggregate gradation 意为“总体分级”，在英语作文中，它可能指的是某种物质或系统的分级结构。总体分级是指将一个整体分解为更小的组成部分，以了解其内部结构和性质。在河流底部的例子中，总体分级可以帮助了解河床的稳定性和吸水能力。
在英语音标中，aggregate gradation的发音为/??gr?d???ɡe??n/。它由三个部分组成：/?/，/gr?d??/和/?ɡe??n/。/?/是一个前元音，发音时舌头放在口腔前部；/gr?d??/是动词grade的过去分词，表示分级或分类；/?ɡe??n/是一个清辅音，发音时需要咬紧牙齿并发出清脆的声音。
aggregate gradation
释义：总体分级，总体分级法

标题： Understanding Aggregate Grading
Aggregate grading is a method used to evaluate the overall quality of a group of items or materials. It is commonly used in the construction industry, where aggregates such as sand, gravel, and soil are used in the production of concrete and other construction materials.
When evaluating aggregate gradation, it is important to consider the size and shape of the materials. Good gradation ensures that the mixture has a consistent texture and flowability, which reduces the potential for voids or excessive packing. Additionally, it ensures that the materials have the correct mechanical properties, such as strength and durability, for the specific application.
In order to achieve good aggregate grading, it is necessary to have a well-organized and systematic approach to sifting, screening, and sorting the materials. This process should be carried out by experienced personnel who are familiar with the specific requirements of the project.
From a practical standpoint, aggregate grading also has implications for environmental sustainability. Good grading practices minimize the waste generated during the production process, reducing the need for landfilling and other disposal methods. Additionally, using high-quality aggregates reduces the need for additional additives in the concrete mixture, which can have negative environmental impacts.
In conclusion, aggregate grading is an essential aspect of ensuring the quality and efficiency of construction materials. It requires a systematic and organized approach to sifting, screening, and sorting materials, as well as a thorough understanding of the specific requirements of the project. Implementing good grading practices can have a positive impact on environmental sustainability as well.
aggregate gradation
Aggregate gradation refers to the distribution of different sizes of particles in a mixture. It is an important parameter to evaluate the quality of aggregate, and it also has a great impact on the construction quality and cost.
In the process of aggregate production, it is necessary to pay attention to the selection of raw materials, grading and classification, and ensure that the aggregate gradation meets the requirements of engineering specifications. If the aggregate gradation is not accurate, it will lead to problems such as excessive fine aggregate and insufficient coarse aggregate, which will affect the quality of concrete and other construction materials.
In addition, aggregate gradation also has a certain impact on the construction process and cost. If the gradation is too coarse, it will increase the transportation and processing costs, and if it is too fine, it will affect the workability and strength of construction materials. Therefore, it is necessary to carefully consider the aggregate gradation in the design and production process to achieve a balance between quality and cost.
In my opinion, aggregate gradation should be considered from multiple perspectives, including environmental protection, resource conservation and economic efficiency. We should use recycled materials and other sustainable resources to reduce waste and environmental pollution, and also strive to achieve a fine balance between quality and cost through optimal gradation design.
In conclusion, aggregate gradation is an important factor that affects the quality and cost of construction materials. It requires careful consideration in the design and production process to achieve a balance between quality and cost, while also considering environmental protection, resource conservation and economic efficiency.
