Leca Lightweight Expanded Clay Aggregate for Building Blocks

LECA Lightweight Expanded Clay Aggregate for Building BlocksLECA (Light Weight Expanded Clay Aggregate) is a Lightweight Expanded Clay, formed by the heating and firing of clay in a rotary kiln, at temparatures of up to 1150°C. The process transforms the clay into various lightweight ceramic granules, which have a hard ceramic shell and a porous core.Product name: Lightweight Expanded Clay Aggregate ( LECA) Other Name: Ceramsite, Expanded Clay, Clay Pebble, Clay pellet, Clay balls.Main Sizes:  -1-4mm(1-3mm), 4-10mm(3-9mm), 8-10mm, 8-16mm, 10-30mm etc.Characteristic: Made of 100% natural clay. Pebbles are of uniform, round shape.  Inert, pH-neutral, clean and decorative.  Specification:Physical Properties:Sizes Water absorption%StackingDensityKg/m3The cylinderPressure StrengthMpa2-4mm8.3500-5502.104-10mm10.0370-4001.128-10mm15.2350-4001.108-16mm23.0280-3101.0810-30mm21.0210-2400.92Chemical Properties:SizesSiO2Al2O3Fe2O3CaOMgOLOSS2-4mm60.4718.9014.392.012.22-0.414-10mm61.1218.7714.211.782.37-0.408-10mm62.2518.8614.322.052.52-0.398-16mm62.5519.7413.772.191.99-0.3810-30mm62.5619.1614.362.271.75-0.25LECA can applies widely for:InsulationBulk fillingPre-cast panel / Unit bath / FacadeBuilding blocksComposite section constructionPartition wall, sound insulation, heat insulator and moist barrierConcrete panel etc.Usages and requirement of LECA lightweight concrete is similar to those of the normal concrete.The structure of LECA lightweight concrete is similar to the normal concrete, mixing with LECA sand (or light sand), cement and water. With proper and sufficient vibration, low air content exist within LECA lightweight concrete and this can also against the corrosion of steel reinforcement. Suitable additives can be added into LECA aggregate concrete.  Packing & Delivery1) 50 Litre PP/PE per BagColorful Printing is Available, 640bags/20'GP, 1360Bags/40'HQ  2) Pallet Packing 24Bags or 28Bags/Plt,  320Bags/20'GP, 1040Bags/40'HQ  3)1150L Jumbo bag  44Bags/40'HQ  4) OEM package1L, 2L, 2.5L, 5L ,10L ,25L, 40L, 45L, 50L etc.Our Service  Ningshu Service: High Quality, Good Service, Competitive Price, Delivery On TimeSample Policy: Free sample is ready on your request, you just need to pay the freight costCustomized service: All products size and package can be costomized according to your requirementsPayment Term:T/T, Western Union, Paypal (for sample)Trade Terms:FOB, CFR, CIFDelivery time: 10-15days after the deposit received    /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
