Video from the scene released by news agency Press Trust of India showed the injured being carried to safety above piles of collapsed building materials and rubble. The video also showed the injured being treated at Sengareddy Government Hospital.

According to reports, the accident occurred while workers were laying a concrete roof when a slab suddenly collapsed. After the accident, people working on the iron structure fell, and some workers working below were trapped in the rubble. Local media reported that many workers were seriously injured.

India Asia News International quoted Sengareddy Police Superintendent Rupesh as saying: “The incident occurred around noon on the 7th. One worker died in the accident, and one injured was seriously injured.”

The Press Trust of India said the worker who died was from Myanmar. Project engineers and contractors have been detained, the report added.

There are some reasons why a building may collapse, such as:

Uneven settlement of buildings: This may cause cracking or damage concrete structures.

Temperature Shrinkage Cracks: Cracks may develop because of shrinkage of concrete caused by temperature changes.

Cracks are caused by materials or construction and design reasons, such as too much fly ash and mineral powder in concrete, too sparse spacing between steel bars, wrong position of negative bending moment bars, unqualified raw materials for steel bars, etc.

Effect of Polycarboxylate Superplasticizer in Concrete

In high-performance concrete, building and construction engineering and precast concrete, anti-slump polycarboxylic acid superplasticizer can improve the mechanical properties, durability, and corrosion resistance of concrete to meet the requirements of high strength and high durability.
