AAC WORLDWIDE %u2022 3.2025 SCIENCE & INNOVATION 29ed concrete blocks with a dry bulk density in the range of 300-331 kg/m%u00b3 and a compressive strength %u2265 2.5 N/mm%u00b2, while the interior walls are constructed from 240 mm thick calcium silicate blocks. Analysis and verification were carried out using the MINEA [5]software package for a maximum spectral acceleration on rock at the building site of SaP,R = 1.94 m/s2. Using only unreinforced masonry results in failure of four ground-floor walls. By using formwork blocks with integrated reinforced concrete columns, a 36% increase in load-bearing capacity was achieved, which allows for a successful verification of structural safety. The installation of non-load-bearing partition walls with a thickness of 115 mm made of AAC blocks with a dry bulk density in the range of 500-550 kg/m%u00b3 and a compressive strength %u2265 5.0 N/mm%u00b2 using the INODIS-P profile is easily possible, since the design seismic acceleration according to EN 1998-1 [3] on the upper floor is 2.1 m/s%u00b2 and significantly lower than the maximum capacity of 8 m/s%u00b2 verified through experimental tests [4]. %u25cfReferences[1] Eurocode 2: Design of concrete structures %u2013 Part 1-1: General rules and rules for buildings, European Committee for Standardization, 2004.[2] Eurocode 6 - Design of masonry structures - Part 1-1: General rules for reinforced and unreinforced masonry structures,European Committee for Standardization, 2005.[3] Eurocode 8: Design of structures for earthquake resistance %u2013 Part 1: General rules, seismic actions and rules for buildings, European Committee for Standardization, 2004.[4] K%u00f6ber.

Auflage, Stand: 06/2023.At Masa we think of nothing but concrete %u2013 and how to shape it for the building materials industry. The machines we design and build are used to produce aerated concrete blocks and panels and sandlime bricks as well as concrete blocks, pavers or landscape products. In other words, we are real concrete heads with a passion for reliable, high-performance machines. Bj%u00f6rn, one of our clever concrete heads, has connected the information worlds of the operational and management levels in AAC plants in the Masa Production Reporting System (PRS). Tailored to the respective target group, the system provides access to all relevant data and conditions from mixing to packaging. When it comes to digitalization in your plant %u2013 Just ask the concrete heads!Customers demand continuous improvement in the coordination of work processes, tasks and resources. %u201cMy milestone connects two target groups in one system.
