Abstract

Methods and machines for making concrete Especially, but not limited to a block Compound with a reflective faceplate, the block was made by dry casting technique. Where the ingredients for the block It has a water / cement ratio of less than or equal to 0.35 in combination with a tightening load to meet the requirements of the block. About strength Withstand the compressive loads specified in BS 6717 Part 1: 1993:

Claims (1)

1. Method for making concrete block consists of preparing a base mixture with Water / cement ratio Less than or quite equal to 0.35 pouring the base mixture. Into templates and compression It is mixed by a vibratory compacting force, where the face plate mixture is poured into the template before the compacting force is applied, so the base mixture and the face plate mixture are pressed and where The base ingredients are pressed before Applying a compacting force to form a cavity that is determined by the base mixture and the template where the faceplate mixture is poured into it. 2. The method as claimed in claim 1 where the binder is Held between Base ingredients and plate ingredients Pre-compacted 3. Method as requested in the claim No. 1 or 2 any of the ingredients. The face plate includes reflective material 4. Method as requested in the claim 1 or 2, any one where the ingredients The front plate is arranged on the surface. Of it with reflective material before being compacted. 5. Method as requested in any of the above claims One where the ingredients The base was shaken before the force was applied. Packed to help increase the filling effect in the template and To be packed later 6. Method as requested in any of the above claims One where the preparation Base ingredients Including cement mixing With granite debris up to 9 mm in diameter and sand particles up to 5 mm in diameter to increase the bonding properties of the block 7. Machine for performing the methods described in clause hold Any of the above rights One of these includes Mixing solution for mixing base ingredients and face ingredients. A template kit that includes a template and equipment for getting the base part and the face part mixture. And convey the base ingredients and Face plate ingredients Go in the template and A hammering device for supplying compacting force to the entrained ingredients in the template 8. Apparatus as requested in Clause 7, where the template set includes the shaking device. For shaking the template to help increase The effect of filling in the template and the subsequent compacting 9. The machine as requested in Clause 7 or 8, where the hammering device is used to Pay a vibratory compacting force 1 0. The machine as requested in any of Clause 7 to 9, where the device Enter, including two components for The base mixture and the face mixture are retained respectively.The feed mechanism is positioned so that the components are on opposite sides of the template and are used in order to be moved. Alternating on the template For separate dispensing of base and portion ingredients Mix the page portion within Template 1. 1.Concrete block made in accordance with the method specified in Clause 1 to 6, any one.
