项目摘要

The drying shrinkage and the concrete spalling during the catastrophic fire can lead to serviceability and the structural failures, in particular, for ultra-high performance concrete (UHPC). UHPC is a new and versatile concrete, yet, its extensive application is hindered by high materials cost and high adverse impact on environments. The key objectives of the proposed project are to develop novel, innovative, crack-resistant, fire-resistant, low-cost, user and eco-friendly, lower energy, low carbon footprint, sustainable and durable Ultra High Performance GeoPolymer Concrete (UHPGPC) using Recycled Steel Fibres derived from waste Tyres (RTSF) and Recycled Aggregates (RA). This will lead to "UHP.RTYF.Geo-Crete" which can be used as slabs on grade for the large industrial floors and tunnels amongst other applications. This project will investigate the shrinkage cracking and the fire-induced spalling mechanisms, the fibre-matrix compatibility, durability, thermal, physical, mechanical, and the micro-structural properties through the multidisciplinary investigations including, FTIR, SEM-EDS, TGA-DTA, XRD, MIP and X ray CT scanning. Also, it will deal with the present challenges of UHPC viz., higher materials cost; CO2 emissions; depletion of restricted natural aggregate resources; pollution of environment, soil, surface and sub-surface water as well as health hazards associated with the unsystematic disposal of discarded tyres, industrial wastes and Construction & Demolition Wastes (CDW). The University of Sheffield, U.K. is world leading in Fibre Reinforced Concrete (FRC) design and re-using wastes in concrete. It will also offer a broad and comprehensive training to the fellow in order to establish her as an independent researcher.
火灾后混凝土的干缩和剥落会导致混凝土的使用性能和结构破坏,特别是超高性能混凝土。超高性能混凝土是一种新型的多功能混凝土,但其广泛应用受到材料成本高和对环境影响大的限制。拟议项目的主要目标是开发新颖,创新,抗裂,耐火,低成本,用户和生态友好,低能耗,低碳足迹,可持续和耐用的超高性能土工聚合物混凝土(UHPGPC),使用来自废轮胎(RTSF)和再生骨料(RA)的再生钢纤维。这将导致“UHP.RTYF.Geo-Crete”,可用作大型工业地板和隧道等应用的地面上的板。本项目将通过FTIR、SEM-EDS、TGA-DTA、XRD、MIP和X射线CT扫描等多学科研究来研究收缩开裂和火灾引起的剥落机理、纤维-基体相容性、耐久性、热、物理、力学和微观结构性能。此外,它还将处理UHPC目前面临的挑战,即,材料成本较高;二氧化碳排放量;有限的天然骨料资源的消耗;环境、土壤、地表水和次地表水的污染以及与废弃轮胎、工业废物和建筑和拆除废物(CDW)的无系统处置有关的健康危害。英国谢菲尔德大学是世界领先的纤维增强混凝土(FRC)设计和再利用混凝土废物。它还将为研究员提供广泛和全面的培训,以使她成为一名独立的研究员。
