Zusammenfassung:	FIELD: manufacture of building materials. ^ SUBSTANCE: invention relates to manufacturing building parts, articles, and structures designed for protection against ionizing emissions. Especially heavy concrete contains following components, wt %: sulfur 6.46-6.61, carbon black 0.02-0.03, paraffin 0.02-0.03, asbestos fiber 0.13-0.28, filler (ferroboron slag with specific surface 150 m2/kg) 10.68-10.93, and aggregate (lead shot with particle diameter 3-4 mm) 82.14-82.67. ^ EFFECT: enhanced crack growth resistance, strength, waterproofness, and frost resistance.
