Ignimbryt jest miękką skałą wulkaniczną stosowaną w historycznych budowlach, a obecnie wykorzystywaną również do wykonywania elewacji budynków. W pracy zbadano wpływ dodatku ignimbrytu, perlitu, pumeksu i zeolitu na ekspansję zapraw wywołaną reakcją alkaliów z krzemionką. W pracy zastosowano przyspieszoną metodę podaną w normie ASTM C1260. Cement portlandzki zastępowano dodatkiem wspomnianych pucolan w ilości 5, 10, 15, 20, 25, 30, 35 i 40%. Uzyskane wyniki pokazały, że ekspansja zapraw malała wraz ze wzrostem zawartości tych pucolan. Wykazano, że 30% dodatek ignimbrytu może ograniczać ekspansję wywołaną reakcją alkaliów z krzemionką. Ponadto stwierdzono, że spośród zbadanych pucolan zeolit jest najbardziej skutecznym dodatkiem ograniczającym ekspansję.

Ignimbrite is a soft volcanic rock which was generally used in historical buildings and as an plaster of contemporary buildings. In this study the effect of ignimbrite, perlite, pumice and zeolite powders addition on the mortars expansion caused by the alkali-silica reaction was investigated. The accelerated mortar bars test was applied according to ASTM C 1260. Ordinary Portland cement was replaced by aforementioned powders in the quantity: 5, 10, 15, 20, 25, 30, 35, and 40%. The obtained results showed that the length change of mortar bars was decreasing with the increasing content of natural pozzolanas. It was determined that the ignimbrite powder replacing 30% of cement can controi the ASR expansion. Moreover, it was found that zeolite powder is the most effective pozzolana to reduce the ASR expansion among other pozzolanas used in this study.
