It involves a thin plate 100mm x 100mm x 1mm thick with rough surfaces on which grout, providing it has some cohesion, can stick. Depending on the real injection setting, the plate surface can be structurally adapted by different grooves, streaks and holes in 网页Test results showed that the dosage of bentonite had a significant effect on the fluidity, rheological properties and compressive strength of grout. The increase in the dosage of bentonite led to increasing the values of flow time, plate cohesion meter, yield stress and plastic viscosity, and reducing the mini-slump results, the static bleeding 网页The cohesion of the grout was determined at 8 ± 1 min with a Lombardi plate cohesion meter [14]. A thin galvanized steel plate (100×100×1 mm) was immersed in the grout and hung on a stand placed on an electronic balance. The mass of the grouts that remains on the plate were recorded when the dripping of the grout had 网页2017年8月25日 ated by the mini-slump ß ow, marsh cone ß ow time, Lombardi plate cohesion meter, yield stress and plastic viscosity values. The key parameters investigated were the dosages of nano-silica and superplasticizer. Test results showed that the dosage of nano-silica had signiÞ cant effect on the ß uidity and rheological properties of grout. 网页Test results showed that increasing replacement level for the RHA amount increases marsh cone flow time, plate cohesion, plastic and apparent viscosity, and the yield stress, but also decreases mini slump diameter. Shear thickening and pseudo-plastic behavior was observed for high RHA content for w/b ratios greater than 1.00. 网页Cohesion Testing System Read more; Flow Cone With Stand Read more; Newsletter Signup.

Several characteristic quantities (including, but not limited to, the marsh cone flow time, the mini slump spreading diameter and the plate cohesion meter value) have been measured for different percentages of these additives.
