一、碳化试验的目的 1.研究现存钢筋混凝土结构物可继续使用的年限,或因承载能力、耐久性存在严重问题而需维修时的维修方法; 2.在实验室研究新品种水泥、骨料、混合材料和特殊配合比设计以及装修材料防止碳化的效果。二、试验的程序和注意问题 1.现场碳化试验的程序和注意问题 (1)测定点的确定认为损害均匀时,在每一层柱及梁的角部和墙及地板的中部各选三个测点。认为损害不均匀时,损害严重的楼层,可从损害严
First, the purpose of the carbonation test 1. To study the number of years for which existing reinforced concrete structures can be used, or for maintenance methods when there are serious problems in bearing capacity and durability; 2. To study new types of cement and aggregates in the laboratory , mixed materials and special mix design and decoration materials prevent carbonization. Second, the test procedures and attention problems 1. On-site carbonation test procedures and attention issues (1) determination of the determination of the point that the damage is even, in each column and beams of the corner and the wall and the middle of the floor selected three Measuring point. When the damage is considered to be uneven, damage to the floor can be severe.
