Composition design method of limestone powder-containing anti-TSA cementing material for tunnel concrete
The invention discloses a composition design method for a limestone powder-containing anti-TSA cementing material of tunnel concrete. The composition design method comprises the following steps: step 1, determining a TSA erosion environment grade of tunnel structure concrete; step 2, determining the mass dosage WCM of a high-activity cementing material in per cubic meter of concrete; step 3, determining the mass ratio RC3A of tricalcium aluminate in the high-activity cementing material; 4, determining the use type and composition of the high-activity cementing material; step 5, determining the mass dosage WLS of the low-activity cementing material stone powder of the concrete per cubic meter; and step 6, determining the composition and the mass ratio of the single-square concrete cementing material. All the materials involved in the method are mature materials, so that the materials are convenient to take, the quality is controllable, and indexes are easy to obtain. Meanwhile, the method can provide corresponding material composition design for different low-temperature sulfate erosion environments, is high in pertinence, covers most of low-temperature sulfate environments, and has wide popularization and application prospects.
