    Abstract: A deflection gauge configured for use with a floor test apparatus is provided. The gauge includes a housing, a string potentiometer mounted on the housing, and a channel extending from the housing and pivotably supporting a pivot beam. The pivot beam has a contact button at one end and an attachment point on an opposite end configured for receiving a string of the potentiometer. Deflection of the contact button due to floor sample weight stresses causes the attachment point to pivot and cause linear extension of the string, which is measured by the potentiometer.

    Abstract: A method of making a rapid setting composition for cement boards is disclosed. Compositions including a hydraulic cement preferably portland cement, an alkali metal citrate such as tripotassium citrate, and a phosphate such as sodium trimetaphosphate, with optional gypsum, and no alkanolamine accelerant, and no fly ash based cement. An interaction between the alkali metal citrate and the phosphate increases the effectiveness of accelerating reactions of the portland cement without need for an alkanolamine accelerant, even in the presence of gypsum. This allows unexpected quick setting and increased early-age compressive strength without shrinkage in the cement board compositions.
