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

Cloud Cycle Ltd，由Emeso Ojo博士领导穆罕默德·伊斯梅尔博士（项目负责人）（技术负责人），Geraldine Hodges（商业领先）和艾德沃博士（工程领导），是一家英国混凝土技术中小企业，为新拌混凝土行业开发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，客户的过量订购或无效的质量控制措施导致未使用的新混凝土返回到配料厂。从全球范围来看，据估计，约1-13%的废弃混凝土是在建筑过程中产生的，每年约为400亿英镑。由于混凝土生产过程中的二氧化碳排放量很高（约占全球排放量的7%），混凝土生产商一直面临着如何实现废物最小化和资源效率的挑战。为了应对这一挑战，Cloud Cycle提出开发一种具有成本效益的监测系统，能够测量新拌混凝土的水灰比、屈服应力和塑性粘度。对混凝土的可施工性（浇筑、压实、修整）和性能有帮助的材料特性。

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.
