Concrete is the most widely used building material in the world - three tons is used for eachhuman on the planet in new build and repair of existing structures. Concrete is composed ofcement powder, aggregates and water. Cement reacts with water bonding the aggregates andcausing concrete setting and hardening.In building large structures, it is important that enough time is allowed for the strength of oneconcrete layer to build up before the next is applied. However, serious construction delaysresult and costs are incurred if too much time is given. It is therefore surprising that nowadaysdestructive or off-site tests are performed on a regular basis to measure concrete strengthduring construction. Measuring water content rapidly on-site would provide such a measuremore efficiently and minimise costs.Subsequent degradation is generally linked to transport of water into or out of the structure.Without being able to assess state of water in concrete, it is again not possible to minimisedegradation repair costs and concrete used for refurbishment.We believe that there is an opportunity to develop a new low-cost, purpose-designed, portabletool for this purpose that could be used either on-site or in test-house laboratories by nonspecialistengineers and scientists. It builds on ten years collaborative work between theUniversity of Surrey, cement production companies, and most recently the National PhysicalLaboratory to use and define Nuclear Magnetic Resonance (NMR) instruments to quantifyand characterise water in cements. NMR is the technology behind medical MRI scanners.MR Solutions proposes to capitalise upon this work to develop a portable NMR instrument foron-site use by the construction industry. This project will produce an assessment of thecommercial viability of this type of instrument and the appropriate routes-to-market andbusiness-model(s) for supply.

混凝土是世界上使用最广泛的建筑材料-地球上每个人在新建和修复现有结构中使用三吨混凝土。混凝土由水泥粉、骨料和水组成。水泥与水起反应，使骨料粘结起来，使混凝土凝固和硬化。在建造大型建筑物时，重要的是要有足够的时间使一层混凝土的强度在下一层混凝土上形成。然而，如果给予太多的时间，就会造成严重的施工延误和费用。因此，令人惊讶的是，现在定期进行破坏性或非现场测试，以测量施工期间的混凝土强度。现场快速测量含水量将提供更有效的测量方法，并最大限度地降低成本。随后的退化通常与水进出结构的运输有关。如果无法评估混凝土中的水状态，则不可能最大限度地降低退化修复成本和用于翻新的混凝土。我们相信，有机会开发一种新的低成本、专门设计的这是一种便携式工具，可供非专业工程师和科学家在现场或试验室实验室使用。它建立在萨里大学，水泥生产公司和最近的国家物理实验室之间的十年合作工作的基础上，使用和定义核磁共振（NMR）仪器来量化和消除水泥中的水。核磁共振是医疗核磁共振扫描仪背后的技术。MR Solutions建议利用这项工作开发一种便携式核磁共振仪器，供建筑行业现场使用。该项目将评估这类仪器的商业可行性，以及适当的市场途径和供应商业模式。
