PURPOSE:To expand a measurement range and to improve measurement precision by measuring the slump of concrete being kneaded on the basis of the scale of the slump to the absolute value of a load during the concrete kneading obtained on the basis of plural past data. CONSTITUTION:When the kind...
Monitoring of the strength gain of concrete using embedded PZT impedance transducer By monitoring the PZT admittance (inversion of impedance) signals and measuring the compressive strength of concrete cubes in different ages, and by ... D Wang,H Zhu - 《Construction & Building Materials》 被引量...
anondestructive concrete test technology means to test and calculate the strength, uniformity, continuity, durability of the concrete via testing measuring directly on the structure without influence to the force and usage of the structure. 非破坏性的具体测试技术手段通过测试的测量测试和计算力量、均一...
Characteristic of concrete strength and elastic modulus was angel·sized. Effect of compensation-shrinkage concrete was 具体力量,弹性模数,收缩的实验。 蠕动完成。 被测试的具体是等级C40报偿收缩混凝土从南津g大平台获得体育中心。 具体力量和弹性模数的特征是天使·估量。 报偿收缩混凝土的作用被评估了。 具体...
This AASHTO standard [AASHTO T353-14] is important for industry since a major factor in the strength of concrete is the particle size distribution of cement (see here), so that it must be measured accurately. The standard specifies (i) the complex refractive index to be used for the partic...
the accurate measurement of bonding strength between carbon fiber and concrete, on the basis of the principle of the static force equation, the quantitative relationship between the tensile strain in carbon fiber and the shearing strength of the concrete was derived under the tensile status ultimately...
The standard DIN EN 206 assumes concrete structural components to have a service life of at least 50 years. Corrosion of the steel reinforcement in ferroconcrete caused by its exposure to CO2 (carbonation) can shorten the service life. Holcim HüttenZem
