1120 Lightweight Aggregate Manufacturing 11201 process description12 lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block structural concrete and pavement the standard transferred to hoppers from the hoppers the material is fed to a rotary kiln which is fired with coal coke natural gas Rotating Kiln An Overview Sciencedirect Topics The tosco the oil shale corporation process used a rotating kiln that was reminiscent of a cement kiln in which heat was transferred to the shale by ceramic balls heated in an exterior burner figure 46 whitcombe and vawter 1976the process which was initiated in the 1960s and 1970s and developed by the oil shale corporation is more correctly described as a retortingupgrading process Lightweight Aggregate Production Process The raw material is processed by heating in rotary kilns at temperatures in excess of 2000 f under carefully controlled conditions the result is a structural grade ceramic lightweight aggregate that is screened to produce precise gradings required for use in asphalt surface treatments structural lightweight concrete concrete masonry Rotary Kilns In Expanded Clay Aggregate Production Rotary kilns are available in either a direct or indirectfired configuration and are often referred to as a calciner the production of expanded clay aggregates is typically carried out in a directfired kiln in which the clay and products of combustion are in direct contact with each other Introduction Structural Concrete Norlite Lightweight Structural lightweight concrete is a versatile building material typically with unit weights from 90 to 125 pounds per cubic foot and compressive strengths from 2500 psi to more than 8000 psi since it is generally 20 to 40 lighter than normalweight concrete a structures dead load can be reduced its foundation costs lowered and its

Understanding Structural Lightweight Concrete Concrete The unit weight of these concretes rarely exceeds 50 psf oven dry at the higher end of the scale are the structural lightweight concretes ranging in weight roughly from 85 to 120 pcf the expanded shales clays and slates produced by both the rotary kiln and the sintering process and expanded slags make up the build of these concrete 213r03 Guide For Structural Lightweightaggregate Roman empire lightweight concrete use was limited until the 20th century when a new type of manufactured expanded shale lightweight aggregate became available for commercial use stephen j hayde a brick manufacturer and ceramic engineer invented the rotary kiln process of expanding shale clay and slate when clay bricks are manufactured it Highstrength Structural Lightweight Concrete One way is to incorporate a lightweight aggregate natural lightweight aggregates such as pumice most widely used scoria volcanic cinders tuff and diatomite or artificial aggregates or rotary kiln produced lightweight aggregates such as expanded clays slates slag perlite or shales cenospheres Manufacturing Of Portland Cement Process And Materials The manufacture of portland cement is a complex process and done in the following steps grinding the raw materials mixing them in certain proportions depending upon their purity and composition and burning them to sintering in a kiln at a temperature of about 1350 to 1500 c during this process these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of Stephen J Hayde Father Of The Lightweight Concrete Nevertheless the concrete was in generally good condition and shows what can be expected of concrete made with rotarykilnproduced lightweight aggregate producing a legacy haydes research which began about 1897 had established by 1917 the basic parameters for aggregate production that led to our modern lightweight concrete industry
