Blesscon Lightweight Bricks Earn 2 SNI Certificates In 2022

PT Superior Prima Sukses, through its lightweight brick product Blesscon, has once again achieved the Indonesian National Standard (SNI) certification from the National Standardization Agency (BSN). This time, Blesscon lightweight bricks obtained the SNI 2156:2021 Autoclaved Aerated Concrete (AAC) Specification, following a previous certification for SNI 8640:2018 specifying lightweight bricks for walling.
Henrianto, the Commercial Director of PT Superior Prima Sukses, explained that the testing parameters for this category include the external surface and physical requirements, such as average compressive strength, individual compressive strength, water absorption, thickness, and dry shrinkage. Additionally, for the Autoclaved Aerated Concrete (AAC) specification, the testing parameters are extended to include modulus of elasticity and heat resistance properties.
Both testing parameters are crucial concerning building safety. The modulus of elasticity measures how elastic a material is to the force applied to its surface. For example, during an earthquake, a material with a higher modulus of elasticity is less prone to cracking or collapsing.
"Through testing, we ensure the quality standards of Blesscon. If any deficiencies are identified, we upgrade them. However, we are grateful that, despite the testing for SNI 2156:2021, Blesscon still meets the quality standards," said Henrianto in a written statement on Wednesday (14/12/2022). He emphasized that having two SNI certificates plus the Green Label certification (environmentally friendly) helps educate the Indonesian market regarding the role of lightweight bricks in building quality.
According to him, when comparing red bricks and lightweight bricks, both have significant differences. It's not just about cost efficiency and construction speed; safety factors also differ.
"For earthquake-prone areas, earthquake-resistant construction cannot be separated from lightweight bricks. Houses built by the government for earthquake victims have standards for construction with lightweight brick walls. There are two advantages. First, the elasticity that prevents the walls from easily bending and collapsing. Second, the weight of lightweight brick walls, which is 1/3 of red brick walls, reduces the risk of serious injuries if they collapse," he said.
Similarly, in the event of a disaster such as a fire, lightweight bricks tend to withstand heat longer, slowing down the rate of fire spread. According to him, this can provide time for emergency responders to extinguish the fire if a fire disaster strikes a residential area.
He added that the advantages of lightweight bricks also have a positive impact on consumer confidence. This is evident in the increased production of three Blesscon lightweight brick plants, which currently reaches 2.7 million cubic meters.
"Next year, we will add more in Krian, Mojokerto, reaching 3.2 million cubic meters. So, the projected increase is 15%," he concluded."
