2 之 On heating the concrete, some of this fixed water in the aggregate may be lost. Lemonite and goethite are reliable sources of hydrogen as long as shield temperature does not exceed 200°C, whereas serpentine is good upto 400°C. The physical properties of high density aggregate are shown in Table 23.1 below.
WHAT ARE THE PROPERTIES OF AGGREGATES FOR
2016年10月1日 Engineering Properties of Aggregates. Aggregates are used in concrete to provide economy in the cost of concrete. Aggregates act as filler only. These do not react with cement and water. But there are properties or characteristics of aggregate which influence the properties of resulting concrete mix. These are as follow.

Properties of Aggregates: Check 5 Properties of Aggregates
2022年8月22日 The properties of aggregate are the essential factor that helps in deciding which type of aggregate will be used in building material. Aggregate is the inert material used to increase the volume of concrete, used as filler material, and for strengthening material in the concrete. It covers 70 to 80% volume throughout the volume of concrete.
