Abstract
Fine and coarse recycled aggregates recovered from demolished masonry and concrete structures were utilized in the manufacture of new
concrete mixtures.Three properties of these new concretes were analyzed:water absorption,total pores volume,and carbonation.The
recycled concrete families were created by replacing parts of the natural aggregates forming families of concrete with 0%,20%,50%,and
100% of aggregates from recycled sources.The usual comparison between mixtures by comparison between behaviors of concrete families.
This research shows that the mix design nomogram (MDN) is a new and useful tool that allows the researchers to compare properties and
behaviors of different concretes.The results show that the family concrete with the highest pore volume and with the same compressive
strength of 20,30,and 40 MPa (2900,4350,and 5800 psi) did not always correspond to the concrete family with the highest degree of
carbonation.This experiment also showed that some compositional characteristics of concrete could have more influence on the durability
that the traditional physical aspects.
Keywords:Absorption; Carbonation; Corrosion; Durability; Waste management

摘要
精细与粗回收总量从拆除砖混和混凝土结构被用来制造新
混凝土混合物.三个属性的这些新的混凝土进行了分析：吸水率,总孔隙体积和碳化.那个
再生混凝土家庭更换部件所造成的自然形成的家庭团聚的具体的0 ％ ,20 ％ ,50 ％和
100 ％的总量从回收来源.通常比较混合物的行为的比较具体的家庭.
这项研究表明,该配合比设计算图（ MDN ）是一种新的和有用的工具,使研究人员比较性能和
行为的不同混凝土.结果表明,家庭的具体最高孔容和相同的压缩
力量20 ,30 ,和40兆帕（ 2900 ,4350和5800磅）并不总是对应于具体的家庭以最高程度的
碳化.这项实验还表明,一些具体的构成特点可以有更多的影响耐久性
,传统的物理方面.
