This study explores the utilization of Waste Latex Paint (WLP) as a sustainable additive in non-structural concrete while addressing key performance criteria by investigating the incorporation of WLP at varied quantities (2 to 20 L/m) while maintaining a 25 MPa compressive strength threshold for low-risk applications. The research investigates the relationship between WLP quantity, compressive strength, and leaching behavior. It explores optimization strategies, including water-to-cement ratio reduction, utilizing paint defoamer and concrete defoamer, and the incorporation of superplasticizers. Analyzing compressive strength and leaching data underpins this investigation, demonstrating the concrete's performance and environmental impact. Optimization techniques facilitate maximizing WLP use while meeting non-structural criteria. The study reveals the positive impact of paint-specific defoamers and superplasticizers on compressive strength. Meanwhile, the addition of superplasticizers broadened potential applications beyond low-strength non-structural elements. Notably, the study reveals that late biocide addition compromised compressive strength without affecting leaching.

使用废乳胶漆进行可持续混凝土设计

本研究探讨了废乳胶漆 (WLP) 作为非结构混凝土中的可持续添加剂的利用，同时通过研究不同数量（2 至 20 L/m）的 WLP 掺入同时保持 25 MPa 抗压强度来解决关键性能标准低风险应用程序的门槛。该研究调查了 WLP 数量、抗压强度和浸出行为之间的关系。它探索了优化策略，包括降低水灰比、使用油漆消泡剂和混凝土消泡剂以及掺入高效减水剂。分析抗压强度和浸出数据是这项调查的基础，展示了混凝土的性能和环境影响。优化技术有助于最大限度地利用 WLP，同时满足非结构标准。该研究揭示了涂料专用消泡剂和高效减水剂对抗压强度的积极影响。同时，超塑化剂的添加拓宽了低强度非结构元件以外的潜在应用。值得注意的是，研究表明，后期添加杀菌剂会损害抗压强度，但不会影响浸出。
