dc.description.abstractСухі будівельні суміші все ширше використовують у будівельних проєктах для здійснення будівельних робіт під час нового будівництва, реконструкції та ремонту. До переваг сухих будівельних сумішей порівняно з комерційними будівельними розчинами належать мінімум кінцевих технологічних операцій для приготування робочого розчину, економія дорогого та енергоємного портландцементу за рахунок використання пластифікаторів та водоутримувальних добавок, стабільність складів сухих будівельних сумішей у результаті точного дозування компонентів і ефективного їх змішування, підвищення продуктивності праці за рахунок поліпшення пластичних властивостей готових розчинів, зниження транспортних витрат. Для виконання робіт із вирівнювання підлогової поверхні для влаштування оздоблювального шару під час нового будівництва та ремонтів використовують сухі будівельні суміші для влаштування підлог, які повинні забезпечити необхідну міцність, довговічність, рівність поверхні стяжки. У статті подано результати із розроблення складів будівельних сухих сумішей модифікованих для влаштування стяжок підлог. Здійснено оптимізацію зернового складу дрібних заповнювачів та карбонатного наповнювача, що забезпечує максимальну щільність упакування зерен у суміші. Показано, що у разі використання суміші заповнювачів на наповнювачах оптимізованого складу та введенні суперпластифікатора у кількості 0,1 мас. % досягається необхідна рухомість розчинової суміші для влаштування стяжки машинним способом. З метою мінімізації витрати портландцементу досліджено вплив кількості в’яжучого на рухомість та фізико-механічні властивості розчинів. Встановлено, що за вмісту портландцементу 26 % досягаються показники міцності затверділого розчину 5,1 та 15,3 МПа через 3 та 28 діб відповідно, а також показники усадки 0,65 мм/м, що задовольняє вимоги чинного стандарту.
dc.description.abstractDry mix mortars are widely used in construction projects for the implementation of construction works in new construction, reconstruction, and repair. The improvement of properties of dry mix mortars for the installation of floor screeds is relevant. The purpose of such mortars is to equalize the differences in the thickness of the floor surface, to create an intermediate layer characterized by the necessary strength, durability, and even surface with the possibility of decoration with various types of flooring. A step-by-step design of the composition of dry mix mortar for the installation of floor screeds was carried out. The ratio of fine aggregates and limestone filler was optimized according to the maximum packing density criterion, the required amount of plasticizer was selected according to the consistency index of the fresh mortar, and the minimum amount of Portland cement was selected to ensure the required strength.
