      摘要
      混凝土骨料是指在混凝土中起骨架或填充作用的粒状松散材料。分粗骨料和细骨料。粗骨料包括卵石、碎石、废渣等,细骨料包括中细砂,粉煤灰等。
      粒径大于4.75 mm的骨料称为粗骨料,俗称石子。常用的有碎石及卵石两种。碎石是天然岩石或岩石经机械破碎、筛分制成的,粒径大于4.75 mm的岩石颗粒。卵石是由自然风化、水流搬运和分选、堆积而成的、粒径大于4.75 mm的岩石颗粒。卵石和碎石颗粒的长度大于该颗粒所属相应粒级的平均粒径2.4倍者为针状颗粒;厚度小于平均粒径0.4倍者为片状颗粒(平均粒径指该粒级上、下限粒径的平均值)。建筑用卵石、碎石应满足国家标准GB/T 14685-2001《建筑用卵石、碎石》的技术要求。粒径4.75 mm以下的骨料称为细骨料,俗称砂。砂按产源分为天然砂、人工砂两类。天然砂是由自然风化、水流搬运和分选、堆积形成的、粒径小于4.75 mm的岩石颗粒,但不包括软质岩、风化岩石的颗粒。天然砂包括河砂、湖砂、山砂和淡化海砂。人工砂是经除土处理的机制砂、混合砂的统称。本设计将用实验数据的方式来对混凝土骨料进行实验分析。

      Abstract
      Concrete aggregates are the granular, loose material that is used to form a skeleton or fill in concrete. Coarse aggregate and fine aggregate. The coarse aggregate includes pebbles, gravel, waste slag, etc., and fine aggregate includes medium fine sand, powder coal ash etc.
      The aggregate size is greater than 4.75 mm and is called a coarse aggregate, commonly known as pebbles. There are two types of gravel and pebbles commonly used. The rock particles are more than 4.75 mm. The pebble is a rock particle which is composed of natural weathering, water moving and sorting, piling up and forming a particle size greater than 4.75 mm. The length of the pebble and the gravel particles is greater than the average size of the particle size of the granule, which is 2.4 times the size of the particle. The average size of the particle size of the particle size is less than 0.4 times the average size of the particle size. The stone and gravel of the building should meet the technical requirements of GB/T 14685-2001. The aggregate size of a grain size 4.75 mm is called fine aggregate, commonly known as sand. Sand is divided into natural sand and artificial sand. Natural sand is made from natural weathering, water handling and sorting, accumulation formation, particle size of rock particles less than 4.75 mm, but not including soft rock, weathering rock particles. Natural sand includes river sand, lake sand, mountain sand and desalination. Artificial sand is a general term for sand and mixed sand that is processed by the soil. The experimental data will be used to analyze the concrete aggregates.
