Developing Sensors and Techniques for Measuring Concrete Water/Cement Ratio and Smart Blending of Concrete

Cloud Cycle Ltd由Emeso Ojo博士（项目负责人）、Mohamed Ismail博士（技术负责人）、Geraldine Hodges博士（商业负责人）和Ed Waugh博士（工程负责人）领导，是一家英国混凝土技术中小企业，为新混凝土行业开发了一种具有成本效益的传感器监测系统。在预拌混凝土生产中，由于客户订货过多或质量控制措施不力，导致未使用的新混凝土返回到批料厂。从全球的角度来看，估计约有1-13%的废弃混凝土是在施工过程中产生的，每年约为400亿英镑。鉴于与混凝土生产相关的高二氧化碳排放（约占全球排放量的7%），混凝土生产商不断面临着实现废物最小化和资源效率目标的挑战。为了应对这一挑战，Cloud Cycle建议开发一种具有成本效益的监测系统，能够测量新混凝土的水灰比、屈服应力和塑性粘度。对混凝土的可施工性（浇筑、压实、整理）和性能有重要影响的材料特性。

Cloud Cycle Ltd, led by Dr Emeso Ojo (project lead), Dr Mohamed Ismail (technical lead), Geraldine Hodges (commercial lead) and Dr Ed Waugh (engineering lead), is a UK concrete technology SME developing a cost-effective sensor monitoring system for the fresh concrete industry.In ready-mixed concrete production, over-ordering by customers or ineffective quality control measures result in the return of unused fresh concrete to the batch plant. From a global perspective, it is estimated that around 1-13% of waste concrete is generated during construction, amounting to approximately £40 billion annually. Given the high CO2 emissions associated with concrete production (corresponding to about 7% of global emissions), concrete producers are constantly faced with the challenge to satisfy targets for waste minimization and resource efficiency.Responding to this challenge, Cloud Cycle proposes developing a cost-effective monitoring system capable of measuring water-cement ratio, yield stress and plastic viscosity of fresh concrete. Material properties which are instrumental in the constructability (pour, compaction, finishing) and performance of concrete.
