It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
This study evaluates sawing waste from six limestone-shell deposits in western Kazakhstan as a fine concrete aggregate. Water absorption (4.13-7.15%) governed mixture water demand (190-275 L/m−3). A power model, W = A·St0.15, described deposit-specific behavior. Optimized mixtures incorporated 1,535-1,690 kg/m−3 of waste and achieved 8.8-38.1 MPa at 28 days. Adding 0.2% polyacrylamide more than halved mixture stiffness and reduced cement demand by approximately 10%.
