L'apparecchiatura Length Change of Restrained Expansion of Mortar and Concrete \u00e8 un sistema di laboratorio di precisione progettato per valutare le variazioni dimensionali e l'espansione frenata di miscele di cemento, malta e calcestruzzo in condizioni controllate. Consente una valutazione accurata degli additivi del cemento, degli agenti espansivi o dei progetti di impasto che influenzano le variazioni volumetriche durante la presa e l'indurimento precoce.<\/p>\n

L'apparecchiatura utilizza stampi in acciaio appositamente lavorati in una configurazione a tre prismi. Ogni stampo \u00e8 dotato di aste di contenimento che limitano la libera espansione, creando un ambiente di deformazione assiale controllata per catturare realisticamente il comportamento delle sollecitazioni interne. Le piastre terminali lisce assicurano un vincolo uniforme lungo la lunghezza del provino, garantendo un'elevata precisione di misura e la stabilit\u00e0 dello stampo durante i test a lungo termine.<\/p>\n

Il sistema \u00e8 in grado di accogliere prismi di malta standard (50\u00d750\u00d7250 mm) e prismi di calcestruzzo (80\u00d780\u00d7240 mm). I comparatori di lunghezza digitali o analogici misurano l'espansione con una precisione di livello micron. I punti di contatto del comparatore sono compatibili con le barre di riferimento standard, consentendo di rilevare minime differenze nei tassi di espansione tra le miscele.<\/p>\n

Tutti i componenti sono progettati ergonomicamente per un uso ripetuto in laboratorio. I dispositivi di fissaggio a sgancio rapido consentono di pulire e assemblare facilmente lo stampo. Gli accessori opzionali comprendono piastre terminali di ricambio, aste di contenimento, barre di riferimento e dispositivi di trasporto. Il dispositivo garantisce una valutazione affidabile, ripetibile e conforme agli standard del comportamento a espansione vincolata dei materiali cementizi.<\/p>","protected":false},"excerpt":{"rendered":"
