The invention discloses a full-recycled concrete high-performance admixture which comprises the following components in parts by weight: 0-100 parts of an ordinary polycarboxylic acid water reducing agent, 0-100 parts of an anti-adsorption polycarboxylic acid water reducing agent and 0-100 parts of a slow-release polycarboxylic acid water reducing agent, and the slow-release polycarboxylic acid water reducing agent is a mixture of 0-100 parts of an ordinary polycarboxylic acid water reducing agent, 0-100 parts of an anti-adsorption polycarboxylic acid water reducing agent and 0-100 parts of a slow-release polycarboxylic acid water reducing agent. The proportion of the slow-release type polycarboxylic acid water reducing agent is set to be 0 to 100 parts. The polycarboxylic acid water reducing agent is prepared by mixing a common polycarboxylic acid water reducing agent, an anti-adsorption polycarboxylic acid water reducing agent and a slow-release polycarboxylic acid water reducing agent which are prepared in different manners, the mixture is added into the concrete prepared in the same manner, and then the concrete added with the polycarboxylic acid water reducing agents prepared in different manners is subjected to experimental recording. The slump, the expansion degree, the initial setting time and the final setting time of the concrete are recorded, the working performance of the concrete is known, the fully-recycled concrete mix proportion design method is verified, and subsequent use of the concrete is more convenient.
本发明公开了全再生混凝土高性能外加剂，包括普通型聚羧酸减水剂、抗吸附型聚羧酸减水剂和缓释型聚羧酸减水剂，所述普通型聚羧酸减水剂的占比设为0份‑100份，所述抗吸附型聚羧酸减水剂的占比设为0份‑100份，所述缓释型聚羧酸减水剂的占比设为0份‑100份。本发明通过采用的聚羧酸减水剂是将不同配制的普通型聚羧酸减水剂、抗吸附型聚羧酸减水剂和缓释型聚羧酸减水剂相互混合制成，并将其加入相同的配制的混凝土中，后为加入了不同配制聚羧酸减水剂的混凝土进行实验记录，记录其塌落度、扩展度、初凝时间和终凝时间，了解其工作性能，验证出全再生混凝土配合比设计方法，更加方便后续使用混凝土。
