Современное строительство немыслимо без бетона, но его главный компонент, портландцемент, уже давно находится в опале из-за своих экологических свойств. У этого материала чудовищно огромный по нынешним меркам углеродный след – при производстве 1 кг цемента в атмосферу выбрасывается столько же углекислого газа. В итоге его доля достигает 8 % от общего объема выбросов CO2, поэтому многие страны намерены отказаться от использования цемента. Но чем его заменить?
Основная функция цемента в составе бетона в том, что он соединяет между собой частицы наполнителя из гравия и песка. Ученые из Токийского университета предложили связывать песчинки друг с другом напрямую, для чего начали экспериментировать с обратной реакцией по получению тетраалкоксисилана. Они прогревали смесь из песка, этанола, гидроксида калия и 2,2-диметоксипропана в разных пропорциях и в течение разных интервалов времени.
После серии экспериментов им удалось получить стабильный материал, напоминающий бетон. Увы, его прочность пока оставляет желать лучшего – вещество крошится в руках. Но ученые не унывают, так как по их расчетам «спиртобетон» можно будет изготавливать с применением широчайшего спектра исходных компонентов, которые не подходят для традиционного строительства. Например, использовать огромные массы песка пустынь, да и вообще почти все, что попадает под определение «песка». Осталось только подобрать подходящий рецепт.
