Rozwój samo-śledzących inteligentnych materiałów dla przemysłu budowlanego jest ważnym zadaniem, mającym na celu ich zabezpieczenie przed zniszczeniem i zapewnienie długiego okresu eksploatacji. W artykule zbadano korelację pomiędzy długością rysy a opornością elektryczną matrycy cementowej zbrojonej włóknami węglowymi stosując trzy-punktowe zginanie próbek i mierząc równocześnie wzrost długości rysy oraz oporność. Znaleziono po raz pierwszy bardzo dobrą korelację pomiędzy tymi zmiennymi dla zbrojonych włóknami węglowymi kompozytów cementowych. Bardzo dobra korelacja liniowa pomiędzy naprężeniem rozciągającym, badanym przy rozłupywaniu próbek, i opornością elektryczną takich samych kompozytów cementowych została także ustalona. Zmierzony bardzo duży wskaźnik określający zmianę oporności elektrycznej w stosunku do długości rysy wynoszący 1435 jest największym wskaźnikiem matrycy w kompozytach cementowych. Kompozyty cementowe opracowane w trakcie tych badań mogą być stosowane do wykrywania rys i odkształceń i ich śledzenia w konstrukcjach betonowych.

Development of self-sensing smart materials for construction industry is an important task to protect the lives and to achieve optimal asset management strategies. In this study, five different carbon fibre reinforced cement matrix composites were designed with carbon fibres having length of 3 mm. In order to investigate the relation between the crack length and electrical resistance change notched three-point bending test was applied to the rectangular prism samples. During the bending test, crack length and electrical resistance were simultaneously recorded. A strong linear relationship was found between the crack length and electrical resistance change. Correlations between the crack length and electrical resistance change were determined for the first time in the literature for carbon fiber reinforced cement composites. Tensile strain and electrical resistance were simultaneously measured during the split tensile tests and a strong linear correlation between the tensile strain and electrical resistance change was determined. The maximum gage factor was obtained at the percolation threshold value due to the shift in the conduction system from post-percolation to pre-percolation by strain. Gage factors as high as 1435 were measured which is the highest gage factor reported for cement matrix composites. The cement composites designed in this study can be used for crack detection and strain sensing in health monitoring of concrete structures.
